- Added keyboard configuration examples for Control-function key detection for rxvt and mlterm to the runtime support library.
- Added script to support Unicode X font installation to the runtime support library.
- Modified xterm start script "uterm" so that with newer xterm versions (from 201) usage of the xterm built-in most recent version of Unicode width data is enabled (which is often more current than the system-provided locale version).
- Provided makefile for Interix.

Feature enhancements:
- Smart arrows added to optional smart input text replacements.
- New word case toggle function Shift-F3 cycling word casing between all small, beginning capital, and all capitals.

#### Change log

    =============================================================================
    Changes from mined 2000.13.2 -> mined 2000.14 (July 2007)
    =============================================

    Text editing features:
    ----------------------
    Case-insensitive search (for all small letters in plain search expression).
    Not applied when searching for an identifier (current identifier occurence,
    HOP F8, or identifier definition, Alt-t).

    New command Alt-x toggles preceding character and its hexadecimal code.

    Control-Del (if properly configured with terminal) on combined
    character deletes only the base character, leaving combining accents
    which may then be combined with the previous character.

    Character encoding support enhancements:
    ----------------------------------------
    Additional sub-options -E? and +E? to just determine the encodings
    of text files or the terminal, respectively, print out information and quit.

    Always separated display of "isolated" combining characters (like for
    all combining characters in "separated" display mode), occuring at the
    line beginning or after a TAB character, which would otherwise be
    hidden or hardly recognisable on screen.

    Tweaked auto-detection of text encoding:
    * UTF-8 vs 8 bit detection is no longer affected by terminal encoding
      (UTF-8 terminal used to set a preference).
      (If auto-detection fails, however, the fallback is still affected
      by the terminal encoding, or the TEXTLANG environment variable.)
    * Improved detection of CJK encodings vs. 8-bit encodings.
    * Added auto-detection of Windows-"ANSI" (CP1252), PC-Latin (CP850), MacRoman.
    * Improved configuration of auto-detection:
      * Less frequent encodings are not detected by default (MacRoman, VISCII).
      * Shortcut "8" in environment variable MINEDDETECT disables auto-detection
        of all CJK encodings.

    Character input enhancements:
    -----------------------------
    New shortcuts Alt-' and Alt-" for input of plain single and double
    quote marks (while in smart quotes mode).

    Interworking enhancements:
    --------------------------
    Terminal encoding handling:
    * Added options -f, -ff, -fff to gradually restrict usage of special
      graphic characters for display of menu borders,
      menu selection highlighting, and the scrollbar.
    * Added options -F, -FF to restrict usage of special characters for
      display of line indications and selected menu items.
    * Detecting and handling non-Unicode terminal with Arabic ligature joining
      (e.g. mlterm in GB18030 or ISO Arabic encoding).
    * Tuned mapped terminal detection to work (as opposed to CJK assumption)
      in a weird case (mlterm with luit).
    * Fixed combining character data version detection for mlterm.
    * Detecting and handling special width behaviour of rxvt and mlterm
      (and different versions of them) concerning unassigned characters,
      non-Unicode characters, and specific width property deviations,
      as well as non-BMP width handling of KDE konsole.
    * Fixed missing suppression of display of an unassigned Unicode character
      (or CJK character mapped to unassigned Unicode character, esp. in GB18030)
      in a CJK terminal. Overridden with +C.
    * Applying display replacement for illegal Unicode characters
      (codes ending with FFFE/FFFF, surrogates, non-Unicode code points).
      Overridden in three levels with +C, +CC, +CCC.
    * Fixed handling of CJK width data in Unicode-based CJK terminal.
      - Added missing check for width data version to CJK auto-detection.
      - Fixed Unicode width function to consider this case.
      - Cleaned CJK width function to be generic based on fixed handling.
      - Added handling of wide characters in Latin-1 range.
    * Ambiguous width handling: properly handling wide display of
      surrogates code points by xterm -cjk_width.
    * Fixed handling of mapped text encoding characters with double width
      on CJK terminal.
    * Fixed input of Control-@ (NUL, used as Mark command) in mapped
      8 bit terminal with different text encoding.
    * Fixed recognised PC terminals (e.g. TERM=cygwin) to override
      UTF-8 encoding assumption by locale environment (auto-detection
      which would otherwise override wrong environment settings does
      not work with most PC terminals).
    * Fixed window title display of non-ASCII characters to work in
      CJK-encoded konsole/gnome-terminal.
    * Fixed display of non-BMP characters in xterm -cjk_width mode
      (which used to work only for plane 2/3/15/16 ranges).
    * Taking care of wcwidth glitch about Yijing Hexagram Symbols.

    Using window focus out/in reports (since xterm 224) to improve
    interpretation of mouse clicks (not positioning the cursor when
    the mouse is just clicked to focus the window).

    Workaround for bug in xterm 224 which would lock up the terminal on
    mouse clicks (due to mouse highlight tracking mode which is now disabled
    for xterm 224).

    Recognising gnome-terminal and disabling usage of fancy menu borders,
    menu selection, and fine-grained scrollbar.

    Recognising more "dark colour terminals" (konsole, gnome-terminal);
    improved visibility of selected menu item on them.

    Usage of terminal capabilites:
    Now mined also considers the termcap information of function key
    escape sequences, in addition to its built-in knowledge of typical
    escape sequences of a large range of terminals
    (where the latter is usually the more effective resource of
    information for recognition of terminal input key escape sequences
    because installed termcap entries are largely incomplete).

    Miscellaneous changes:
    ----------------------
    Increased speed of certain search operations in UTF-8 mode (especially
    starting with ".*") by a factor of ~ 40.

    Discarded option +m.

    Line end indications: By default, line-end indications for DOS and
    Mac line ends will be the same as for Unix line ends but coloured;
    mined uses blue for DOS line ends and yellow for Mac line ends.
    The previous default of distinct line-end indications is preserved
    for black and white terminals.
    Environment variables to configure specific indications are retained
    (MINEDDOSRET, MINEDMACRET, MINEDUTFDOSRET, MINEDUTFMACRET).

    Deletion of combined characters: delete character function tweaked to
    also delete Arabic joined characters with the base character in joining
    terminal (mlterm).

    Enabled key navigation also in Quotes style menu.

    Option -M only suppresses display of the menu header line
    (including flags) (pull-down and pop-up menus can still be opened
    with keyboard commands), but mouse control remains enabled.
    Fixed menu display position in this mode (making menu titles of
    pull-down menus visible).

    Tuned selected menu item marking for terminals than cannot reverse
    display or hide cursor.

    Detecting slow terminal escape sequences (starting with a late '['
    or ']' after an escape) and discarding them (rather than inserting
    garbage into the text).

    Dropped ESC ] variation of the goto marker command.

    Added housekeeping for the position marker file @mined.mar: old entries
    for the current file name are removed. Not used on PC versions (djgpp).

    Bug fixes:
    ----------
    Structured search: added recognition of #elif for C macro bracket searching.

    Fixed password hiding for multiple occurrences of "password" in a line.

    Fixed "HOP -" not to spoil the underlining by applying smart dashes.

    Combined character editing:
    * Fixed positioning after inserting character into combined character
      (substituting the previous base character, also with ESC X or ESC U).
    * Fixed Control-BackSpace within combinined character to delete base
      character.
    * Fixed BackSpace deletion/positioning anomalies when the cursor was
      micro-positioned within a combined character or (after a TAB)
      positioned on an isolated combining character.

    Combined character repositioning:
    * Fixed micro-position within combined character to persist after
      display refresh (ESC .).
    * Fixed micro-position within combined character to persist after
      reloading file (e.g. in new mined session), also after returning to
      a file with Alt-Return (marker stack), after help viewing and checkout.

    Text encoding handling:
    * Added handling of joining characters (Arabic LAM/ALEF) in joining
      terminal (probably mlterm) and non-Unicode text encoding (GB18030 or
      8-bit Arabic); both combined and separated display mode.
    * Fixed handling of auto-detection vs. explicit encoding (-E) when
      editing multiple files.

    Character input support:
    * Fixed ambiguous mnemonics to distinguish between input methods as
      documented (failed in 2000.13); e.g. ^V'' -> right double quote mark,
      while ^V space '' space -> acute accent (RFC 1345 mnemo).
    * Fixed Latin-1/UTF-8 conversion function Alt-Shift-F11 from also
      sometimes applying mnemonic conversion.

    Fixed hint in manual on properly using xterm VT220 keyboard option.

    Enhanced handling of line markers (special line ends) on CJK terminals.

    Manual page: fixed descriptions for command variants "with HOP" in
    command reference which were missing in 2000.13.2.

    Fixed uterm script in case none of LC_ALL, LC_CTYPE, LANG is defined.

    Fixed cygwin version from not restoring tty mode after shell command (ESC !).

    Reenabled shell escape (ESC !) when mined was invoked with redirected
    input (e.g. in a pipe) which could not access the terminal since 2000.2.
    Not working in cygwin version.

    Code revision: further factoring out of functional blocks (file
    operations, text buffer handling).

    Reenabled QUIT signal from keyboard (sent with ^\ key) to interrupt
    search operations (did not work for ~ 10 years).

    Fixed minedmar housekeeping scripts (Unix and DOS). (Also added
    implicit housekeeping, see above.)

    Fixed cygwin version from not assuming "modified" with option -r.

    =============================================================================
    Changes from mined 2000.13.1 -> mined 2000.13.2 (December 2006)
    ===============================================

    Documentation enhancements:
    ---------------------------
    Improved hints on modified function key input:
    * Overview of system-specific limitations and remedies.
    * Additional hint on workaround to use ESC Fn instead of Alt-Fn for
      accent prefix functions.

    Revised HTML manual file to be displayed properly with other browsers
    than Firefox (IE, Opera, konqueror).

    Tweaked man page generation (from HTML manual) to produce improved layout;
    also including ->NEW-> tags in man page.

    Interactive enhancements:
    -------------------------
    Interpreting ESC Fn as Alt-Fn even after ESCAPE delay (for first accent
    key in text input, not on prompt line).

    Character input support enhancements:
    -------------------------------------
    Additional workaround to use Control-V Fn instead of Control-Fn for
    accent prefix functions.

    Added source indications to Input method menu.

    Added information message after switching the input method.

    Made input method tags unique - thus enabled distinguished selection
    between Kazakh and Katakana - and added check for this to makefile.
    (Also added check for uniqueness of character mapping tags to makefile.)

    Input methods:
    * Replaced previous Thai keyboard mapping of uncertain origin with
      slightly different Thai Kesmanee keyboard mapping from m17n.
      (Previous method is still included in the distribution and can
      be enabled by uncommenting its entry in keymaps.cfg.)
    * Re-enabled previous Amharic input method called "Ethiopic" (from yudit)
      but leaving in new input method "Amharic" (generated from Unicode data)
      above it in the menu (as a preferred method according to user feedback).

    Mnemonics and accent prefix keys:
    * Enhanced documentation for multiple accent combinations, and special
      arrangement for accent below.
    * Added additional mnemonic for line below, enabling its input with
      3 times Control-- as a prefix.

    Interoperability enhancements:
    ------------------------------
    Terminal keyboard handling:
    * Reassigned escape sequence ESC [29~ which is emitted by xterm on the
      Menu key to invoke HOP rather than Shift-F6. This provides a more
      easily accessible HOP function for laptops (which do not have the
      right/numeric keypad) and enables assignment of the HOP function to
      the middle keypad key ("5") for KDE konsole which is by default
      deprived from this feature due to a deficiency in the QT framework.
    * Using application keypad mode with xterm 216 or later since modified
      keypad keys (Control- etc) are now distinguished in that mode.
    * Added recognition of modified function keys in xterm HP and SCO keys
      modes.

    Terminal encoding handling:
    * Added terminal encoding detection of FreeBSD console and a number of
      KOI8-R, MacRoman, and ASCII terminals.
    * Fixed filename encoding handling in window title of KDE konsole terminal.

    Terminal screen handling:
    * Tweaked highlighting of selected menu item to ensure good contrast
      on dark terminal background too.
    * In DOS version (djgpp), tweaked highlighting of selected menu header
      to be more consistent with Unix versions.

    Unicode terminal start script:
    * Tweaked uterm (the script to invoke a terminal with best-choice
      Unicode fonts) to not hang if xlsfonts ties up at the server.
    * Fixed uterm to work properly with an explicit -display parameter.
    * Tweaked uterm to add some X resource preferences for xterm when
      invoked with an application (-e). (See uterm manual page for details.)

    Printing:
    * Tweaked printing script uprint to cooperate with newer version of paps.

    Building mined / makefiles:
    * Tweaked some makefiles to work also on systems with the termcap API
      installed only in /lib (not in /usr/lib).
    * Fixed makefile problem when makefile.gcc could be used but not gmake
      (esp. on SunOS without native C compiler).
    * Added hint to INSTALL.DOC to build mined with 64 bit libraries on
      Linux (LIB=64 make) or SunOS (LIB=/64 make).
    * Including pre-transformed version of Radical/Stroke input method
      table in distribution to ensure that mined can be built on Mac OS
      (where generation of this file fails since neither sed nor gcc can
      handle long strings there).

    Bug fixes:
    ----------
    Menu handling:
    * Fixed menu navigation with letter keys which did not work after a
      menu had been opened with a right-click.
    * Fixed middle mouse click on flag (to toggle it) not to apply HOP, so
      especially toggling the input method works with the middle button.
    * Fixed open menu not closing properly after window resizing.

    Fixed display error after deleting a combining character that was
    combined with a TAB character (since 2000.6).

    Fixed printing script uprint to properly report if neither the paps
    nor the uniprint utility can be found (since 2000.11).

    Fixed screen size change handling to work also with ncurses.

    The curses version (minced) could not detect some screen properties
    anymore (e.g. combining character support, since 2000.13.1); fixed.

    In DOS version (djgpp) running in cygwin console, fixed wrong assumption
    about terminal encoding.

    Fixed file name "~" to expand to $HOME, too (like in "~/something"),
    for use with ESC d command.

    Fixed a new instance of inappropriate error messages "Unknown
    character mnemonic" to "Invalid character" (when a valid mnemonic was
    not found on first attempt of the new mnemonic lookup algorithm but
    the character found later cannot be inserted in the current encoding).

    Fixed a crash condition in cygwin version when using the print command.

    =============================================================================
    Changes from mined 2000.12 -> mined 2000.13 (October 2006)
    ===========================================

    Documentation enhancements:
    ---------------------------
    Revised manual structure, featuring more comprehensive new chapters on
    * Structured editing support
    * Character handling support
    * Language support

    Equipped HTML manual version with an auto-navigation index.

    Character encoding support enhancements:
    ----------------------------------------
    Enhanced support for UTF-16 files:
    * Added auto-detection of UTF-16 without BOM (big endian and little endian).
    * Added explicit command line selection of UTF-16.
    Now all big/little endian UTF-16 files with or without BOM can be
    auto-detected and explicitly selected. Copy/Paste when editing a
    UTF-16 file was fixed.

    Updated to Unicode 5.0.0 (final, from beta2 in 2000.12):
    * Cangjie input method codes (as before, supplemented with additional
      mappings from HKSCS-2004 Changjie input code table.)
    * Han information (from Unihan database) for CJK characters (6 fixes),
      now also including Hangul pronunciation (new in Unihan database).
    * Character properties for display indication (one dash association changed).

    When TERM=cygwin, mined assumes a terminal encoding that is reduced by
    those Windows Latin characters which are poorly emulated by cygwin.

    Unicode character code display (ESC u) now also notifies about
    too long UTF-8 encoding sequences.

    Character input support enhancements:
    -------------------------------------
    Revised handling of accent prefix keys; turned implementation generic,
    fixing some inconsistencies in accent combination.
    * Additional accent prefix keys (like Alt-3, Control-3, Control-Alt-3
      etc) as attached to modified digits for Vietnamese input, are now
      applicable also in the prompt line (e.g. for search expressions).

    Added support for multiple accented character input:
    * Multiple accent prefix keys can be combined, so e.g.
      F5 F6 u enters U+01D8 (u with diaeresis and acute),
      Control-2 Control-7 a enters U+1EB1 (a with grave and breve),
      Control-- Control-: u enters U+1E7B (u with macron and diaeresis),
      Control-, Control-( e enters U+1E1D (e with cedilla and breve),
      Alt-7 Control-, alpha
      Alt-F6 Shift-F6 Control-, alpha
      Control-less Control-` Control-, alpha
      all enter U+1F82 (alpha with psili and varia and ypogegrammeni), etc.
    * Generic handling of accent prefix with precomposed base character,
      applying implicit decomposition if needed, so e.g. F6 ü will enter u
      with diaeresis and acute (even without explicitly configured
      mnemonic) etc.

    Added accent prefix keys:
    * Additional accent prefix keys for most frequent accents of all
      Latin-based languages (macron, breve, dot above, ogonek, caron, stroke).
    * Support for convenient combining character input with accent prefix keys.
    * Support for convenient quotation marks input with accent prefix keys.
    * Support for Greek (monotonic and polytonic) by adding respective
      accent keys and accented character mnemonics.
    * Support for Cyrillic accented characters by adding respective
      accent keys and accented character mnemonics.

    Added character mnemonics:
    * Added mnemonics for input of separate Unicode combining characters
      using the newly-introduced accent prefix keys combined with Tab.
    * Additional sets of accented mnemonics for Greek and Cyrillic.
    * New short mnemonics (to be used after Control-V prefix) "zz" for the
      DOWNWARDS ZIGZAG ARROW symbol, "cm" for the CHECK MARK symbol (in
      addition to the "OK" mnemonic from RFC 1345).
    * Alternative mnemonics like "SCHWA" in addition to "Schwa" and
      additional more intuitive ones like "_ou" for Latin small letter ou
      and "_alpha" for Latin small letter alpha.
    * Mnemonics combining accents on precomposed characters like
      "æ'" in addition to "ae'" so if you have "æ" on your keyboard,
      you can now enter Latin ae with acute using it, either with a
      mnemonic sequence (combining it with ') or also using the acute
      accent prefix function (F6 or Control-1).

    Mnemonic input improvements:
    * Fixed entering accent prefix with subsequent non-ASCII character in
      non-Unicode text mode.
    * Enabled entering character mnemonics with non-ASCII characters in
      non-Unicode text mode.
    * Enabled detection of more intuitive accent mnemonics (like ^V"a as a
      two-letter mnemonic) in full mnemonic input mode (like ^V space "a ).

    Input methods:
    * Added keyboard shortcut Alt-I to open Input Method menu.
    * Supporting space and non-ASCII characters in menu names of input methods.
    * Fixed Kazakh input method to use "`" as a prefix rather than "` "
      (as generated from yudit kmap).
    * Included Amharic input method generated from Unicode script range
      Ethiopic, instead of previous Ethiopic mapping (from yudit) or
      Amharic SERA mapping (from m17n) which both seem to be widely
      inconsistent between character mnemonics and Unicode character names.
      (Those other two are included in the distribution, however, and can
      be enabled by uncommenting their entry in keymaps.cfg.)

    Added generation feature for keyboard mappings from m17n input methods
    (*.mim files from the m17n-db package) to the mkkbmap script.

    Interactive enhancements:
    -------------------------
    Improved display of ESC, F1, Control-V, and Han info prompt lines.

    Revised menu structure, improved / added some menu items:
    * File menu:
    	"Discard & Quit" renamed to just "Quit"
    	"Save To" renamed to "Set Name"
    * Edit menu:
    	new item "Paste Other" pastes external buffer
    		(from other instance of mined)
    	integrated edit items from former Extra menu
    * Search menu: renamed to "Search/Go"
    * former Extra menu:
    	split into editing functions (moved to Edit menu)
    	and settings (in new Options menu)
    * new Options menu:
    	gateway items to the flag menus (in case direct opening of flag
    		menus by right-clicking the flag is not intuitive enough)
    	integrated former (DOS-only) Screen menu (now also for Unix)
    		(as a sub-menu)
    	added help items
    		help topics viewer
    		About mined
    		function key help bars

    Revised menu handling system:
    * Pull-down menus and flag menus can also be opened by scrolling the
      mouse wheel on the menu header or the flag indication, respectively.
    * All menus are now scrollable (when window is smaller than full
      menu); implementation of pull-down and pop-up menus was unified.
    * Open menus are now closed when the window is resized in order to
      prevent calculation problems for resizing and repositioning the
      selected item (limitation planned to be removed in future version).

    Reassigned command to invoke system command with paste buffer as input
    (pipe paste buffer into program) from ESC c (deprecated) to HOP ESC !.

    Added script highlighting support to curses version.

    Menu layout, highlighting of selected menu item:
    * Enabled "stylish selection bar" for selected menu item by default,
      as font support seems to have improved; this highlights the selected
      item (during menu navigation) continuously from left to right menu border.
    * Enabled stylish selection bar also for double menu borders (-Qd)
      using adjusted graphic characters.
    * Added option -Qq to disable this layout feature.
    * Highlighting selected item now with coloured background; colour is
      configurable with the environment variable MINEDSEL.

    Added toggle feature for TAB expansion mode (options -+4, -+8, can
    now be changed from the Options menu or the Auto indent menu).

    New commands:
    * HOP ESC T toggles the TAB expansion mode.
    * Alt-F12 toggles the Input method (between current and previous one,
      like left-clicking on the Input method flag indication)
    * Control-F12 opens the Input method menu
    * Control-F2: save current file (if needed) and exit mined; alternative
      to ESC ESC, avoiding without the function key detection delay

    (Fixed from SUSE 10.2 alpha pre-release) In emacs command mode (-e),
    remapped two key commands:
    * ESC ESC now dispatches to the mined ESCAPE commands (Alt-x deprecated)
    * HOP was reassigned to ^\ (as ^^ is now overlayed as an accent prefix key)

    Interoperability enhancements:
    ------------------------------
    Detecting and enabling keyboard escape sequences generated by new
    xterm resource modifyOtherKeys mode (xterm 214/216) which facilitates
    generic detection of Alt/Shift/Control-modified keys (without having
    to setup individual key translations).

    Auto-detecting and supporting xterm resource utf8Title mode (xterm
    213) which facilitates display of Unicode file names in the window title.
    Added resource (value true) to sample file Xdefaults.mined.

    Printing script uprint: Removed dpi option for paps which is not
    supported anymore in newer versions as paps fortunately changed to
    generating outlines.

    Added application note (to manual section "Terminal interworking problems")
    indicating that kterm should be configured to run in either euc or sjis
    mode because its default mode (ISO 2022) is not supported.

    Added setup for keypad support for VT220, xterm emulating VT220 mode
    (assuming proper setting of TERM=vt220), and linux console.

    Added detection of new modified function key codes for F1-F4 (e.g. with
    Control) that seem to have been introduced with xterm 216. (Modified
    F5 etc work as before.)

    Skipping auto-detection of terminal features if the terminal does not
    support ANSI-like escape sequences.

    Added some legacy terminal support:
    * recognition of some legacy function key escape sequences
    * supporting terminals that cannot insert/delete lines (was broken
      since introduction of menus due to the menu header line)
    * supporting VT52 (if indicated properly by TERM environment variable)

    Abandoned the option -A (introduced in 2000.11) as disabling the ESC
    prefix detection may lead to unexpected partial escape sequences
    appearing to the user.

    Added workarounds for display of menu borders in xterm -cjk_width mode
    which has some display bugs with remains of background colour after
    overwriting a character cell.

    File handling enhancements:
    ---------------------------
    When cloning a file (with Save As / Set Name / ESC n / ESC d),
    file permissions (access modes) are preserved and cloned.

    With the +x command line option, new files are given executable
    permission only where read permission is also set.

    Bug fixes:
    ----------
    Fixed misconceived interpretation of "Spacing Combining" character
    category, thus spacing Marks are no longer highlighted (since 2000.11).

    Toggling the text encoding (left click on Encoding flag) was improved
    to always remember the last selected encoding distinct from the current one.

    Fixed locale "vi_VN" to be recognised as UTF-8 encoded.

    Fixed command line option for initial search (+/EXPR) not to check
    (since 2000.3) and interpret (since 2000.7) EXPR as options.

    Fixed handling of backslash in keyboard mapping tables in some cases.

    Revised install targets of makefiles for improved robustness.

    Fixed cygwin makefile install target to consider $(prefix) or $(root)
    for desktop icon, and to include wmined and wmined.bat.

    Fixed makefile to work for installing alias links despite of
    missing main makefile. (Updated in 2000.12.2)

    In cygwin makefile, fixed path to desktop installation script mkicon.
    (Updated in 2000.12.2)

    Added linking of appropriate makefile.* to src/makefile to configure script.
    (Updated in 2000.12.1)

    Tuned screen attributes of curses version to match non-curses version
    better in menus (color usage, invisible cursor, bold border),
    in case anyone would be using the curses version (make minced).

    On cygwin, fixed inappropriate error message "Cannot read paste buffer"
    to "Buffer is empty" if no paste buffer exists.

    Fixed Han info menu not being properly cleared after moving away from
    Han letter which led to incorrect redisplay of old info after screen refresh.

    Fixed occasional screen garbage after inserting with open Han info menu.

    Fixed wrong error message "Interrupted system call" (since 2000.11) when
    trying to paste non-existing buffer after screen has been resized (due
    to static nature of errno which was left untouched in this case and is
    now explicitly set to 0 which is hopefully portable).

    Tuned menu width for partial menu display to be always at maximum width
    of the full menu to avoid irritating border artifacts when scrolling.

    Fixed occasionally postponed correct screen adjustment when updating the
    screen after terminal/window size has changed.

    Fixed failure of workaround for avoiding menu display garbage on bidi
    terminal (mlterm) when display was at top of file.
    Also enabled this workaround for non-UTF-8 encoding, too.

    Fixed -E option without following option parameter from randomly
    selecting a text encoding.

    Fixed near-endless display loop after window was resized to a very
    thin one (since 2000.5).

    (Fixed from SUSE 10.2 alpha pre-release) Multiple accent combinations
    with ambiguous mnemonics for at least one of the accents also work now.

    (Fixed from SUSE 10.2 alpha pre-release) Fixed Alt-H from inserting
    the closing HTML tag at the wrong place.

    (Fixed from SUSE 10.2 alpha pre-release) Fixed prompt for multiple
    accent prefixes to display properly also in non-UTF-8 text encoding.

    Applying explicit workaround for invisible cursor control missing
    from terminfo/termcap data (Sun), enabling nicer menu appearance.

    =============================================================================
    Changes from mined 2000.11 -> mined 2000.12 (March 2006)
    ===========================================

    Interactive enhancements:
    -------------------------
    Enabled display of left shift marker by default (indicating that a long
    line has been shifted out left for display).
    Changed display of left and right shift markers to reverse coloured
    for clearer indication.

    Enabled graphic menu borders in more terminals (also in CJK terminals).

    Two slight reassignments of shifted function keys make room for more
    intuitive assignments:
    * Detached copy function from Control-Ins. Use End/Shift-End instead.
    * Detached function to move to previous/next beginning of paragraph
      from Control-cursor-up/down. Use Control-Shift-cursor-up/down instead.

    After pasting with the Insert key, the cursor is now by default placed
    behind the pasted region.
    To paste and leave the cursor positioning before the pasted region,
    use ^P or Control-Insert.
    See the -V/+V options to change the default behaviour.

    The Alt-Insert function to paste previous buffer(s) (ring buffer function)
    now also works when the cursor stays left of the pasted region.

    Changed the function of left-clicking the Input Method menu to
    toggle between the current and the previous keyboard mapping
    rather than cycle through the mappings (like on the Encoding menu).

    Changed the function of left-clicking the Quote Style menu to
    toggle between the current and the previous quotation mark style
    rather than cycle through the styles (like on the Encoding menu).

    New option +D sets up xterm (by sending dynamic configuration codes)
    to apply two useful keyboard handling modes:
    * Delete key on small keypad sends DEL character rather than an escape
      sequence and can thus be distinguished from the Delete key on the
      big (numeric) keypad.
    * Prepend ESC to character if pressed with the Alt or Meta key in
      order to enable Alt-commands (e.g. Alt-f to open the file menu,
      Alt-Shift-H to enter HTML markers etc).
    (Unfortunately this cannot be done by default as it cannot be undone
    because the previous state cannot be detected.)
    (This xterm setting should rather be configured permanently as
    suggested in the sample file Xdefaults.mined in the
    Mined runtime support library.)

    Character encoding support enhancements:
    ----------------------------------------
    Updated to Unicode 5.0.0 beta2:
    * Case conversion, Script information.
    * Combining character width properties (continuing to work with older
      width data versions by terminal auto-detection).
    * Han information (from Unihan database) for CJK characters.
    * Radical/Stroke input method.
    * Added generic and supplemental character input mnemonics for new
      LATIN characters.

    Supplemented Big5 character set with HKSCS-2004 update from

    http://info.gov.hk/digital21/eng/hkscs/, adding more than 100 characters
    and fixing 5 characters that seem to be mapped incorrectly in libiconv.
    Handling covers mappings to two Unicode characters, like for JIS encodings.

    Revised interpretation of locale environment variables to comply with
    de-facto locale standard. Added environment variable TEXTLANG to
    specify text encoding preference (esp. for new files).
    The order in which environment variables are searched for an
    encoding specification is now:
    (TEXTLANG), LC_ALL, LC_CTYPE, LANG
    where TEXTLANG is only considered for assumed text encoding (with
    precedence over the other variables), while the L* variables are
    considered for setting of the terminal encoding.
    Note however:
    * Explicit command line parameters are available to specify either
      terminal or text encoding. They override environment variable settings.
    * UTF-8 terminal auto-detection overrides other terminal encoding settings.
    * Text encoding auto-detection overrides environment settings but not
      command line settings.
    * Assumed text encoding can be switched while editing as usual.

    Revised and enhanced command-line options to specify encodings:
    -E selects text encoding, +E assumes terminal encoding;
    -/+EX (single-letter tag) uses special tag as before,
    -/+E=charmap uses charmap name (as reported by locale charmap command)
    -/+E.suffix uses encoding suffix as used in locale names
    -/+E:flag uses 2-letter flag used by mined as indication in Encoding flag

    Revised terminal encoding handling to support also mapped 8-bit encodings
    (i.e. non-Latin-1 8-bit encodings like ISO-8859-*, KOI, DOS, Windows etc).
    Handling of combining characters (with auto-detection) is covered.
    (PC character set handling is no longer a special case.)

    Generally revised handling of text and terminal encoding to support all
    combinations of them.
    CJK terminals are no longer restricted to handle text in matching CJK
    encoding only; all encodings (Unicode, other CJK, 8-bit) can now also
    be edited in CJK terminals. However, especially for CJK terminals
    proper display and width handling of characters that are not handled
    by the terminal or not contained in the font cannot always be provided
    although some auto-detection is applied for handling of extended code ranges.

    Supporting lots of additional 8-bit encodings, including all that appear
    to be known by typical locale set installations, for both text encoding
    and terminal encoding. For text encoding, folding less important ones
    into sub-menus of the encoding menu to keep it concise.

    New optional Unicode mode for Copy/Paste buffer which maintains its
    contents always in Unicode, so that Copy/Paste of text works between
    differently encoded files (or sections of a file, if encoding is
    switched while editing) with automatic character code conversion.
    Enable with -Eu or right-click on Paste buffer menu ("="/"+") and
    select "Unicode".

    Character handling enhancements:
    --------------------------------
    Supplemented Cangjie input method (verified for Unicode 5.0.0 beta2)
    with additional mappings from HKSCS-2004 Changjie input code table.
    Enhanced the mkkbmap script to automatically merge Unihan and HKSCS
    generated keyboard mappings into the Cangjie input method mapping table
    (invoke ./mkkbmap cj +).

    Identifier character recognition - also used for word boundaries - is
    now always based on Unicode character categories.

    Case conversion is now always (i.e. in all encodings) based on Unicode.

    With Shift-F3 (or "Word case toggle" from the Extra menu) which cycles
    a word between all small, title case, and all capitals, for title case
    now an actual Unicode title case character is used if available.

    Updated HTML character mnemonics to HTML 4.01. Added make script to derive
    them automatically.

    Smart quotes enabled in all text encodings.

    Tuned Quotes style menu according to new information about international
    typographic quote marks usage.

    Enhanced indication of characters not displayable on the terminal:
    Additional Unicode indications (like 'E' on cyan background for the
    Euro symbol already) for quotation marks and dashes.

    Tweaked mnemonic input support for character mnemonics that already
    contain non-ASCII characters (e.g. for Vietnamese mnemonic input of
    multiple-accented characters) to work also in non-UTF-8 text mode.

    Interoperability enhancements:
    ------------------------------
    Checked mined with kterm.
    Added auto-detection of kterm encoding.

    In rxvt, the two keypad Del keys (small keypad, numeric keypad)
    are automatically distinguished from each other and invoke the
    Delete Character (small keypad) and Cut (numeric keypad) functions,
    respectively (with Control-/Shift-/Alt- alternatives, see manual).

    Fixed screen color handling problem with newer configurations of
    terminfo (ncurses) entries.

    Fixed display of 8-bit encoded files in UTF-8 terminal with
    wide non-CJK characters (xterm -cjk_width).

    Fixed handling of CJK encoded characters in the range 0xA0** as
    extended code points, to prevent bogus display in some terminals
    (transparent display can be enforced with the +CCC option, like for
    other extended code points).

    Fixed handling of JIS characters that map to two Unicode characters
    for printing (ESC f p) and character info display (ESC u).

    Added control strings for more terminals to display the file name
    in the window header.

    Fixed make problem with newer configurations of ncurses when ncurses
    development package is not installed by preferring ncursesw over ncurses.

    Adding -ldl when linking ncurses version (make minced) and libdl library
    exists to fix make problem with newer ncursesw configuration.

    Tweaked environment settings TERM=ansi or ansi-nt to let mined assume
    CP850 terminal encoding (e.g. with Windows command line telnet),
    tweaked TERM=interix to indicate CP850 rather than CP437.

    Further enhancements:
    ---------------------
    The search corresponding command for #if/#else/#endif structures was
    enhanced to consider nested structures.

    Added a few supplementary mnemonics, e.g. for the downwards zigzag arrow.

    Added new password hiding feature which hides all characters behind
    the string "assword" in a line (to accommodate for password and Password).
    Activated with the option -P. Disabled with +P.
    By default, this mode is activated when editing a file whose name starts
    with ".".

    The former option to enable proportional font support was changed to +p.

    Added logic to distinguish CJK locales with the ambiguous encoding suffix
    ".euc".

    Added pico emulation mode (function emulation unfinished).

    Added aliases minmacs, mstar, mpico for invocation of mined in
    emulation modes for emacs, WordStar, pico, respectively.

    Added wrapper scripts umined, xmined for invocation of mined in a new
    separate terminal window. With umined, it will be enforced to be in
    UTF-8 mode (using the uterm script).

    Revised uterm script to invoke a new terminal window in UTF-8 mode with
    suitable fonts. Fixed locale manipulation. Including uterm in default
    installation to system bin directory, also installing a manual page.

    Detecting terminal versions (by requesting terminal device attributes),
    which enables the version-specific application of workarounds for
    terminal bugs.

    Deprecated environment variable MINEDHELPFILE, replaced by MINEDDIR
    which may point to the installation directory of the Mined runtime
    support library (unless installed in one of the typical locations)
    which also contains the uprint script.

    Revised structure of Mined runtime support library, using subdirectories.

    Bug fixes:
    ----------
    Added workaround for the often missing xterm/rxvt termcap entry eA
    (enable alternate character set). Without this workaround,
    menu borders would not be displayed correctly in VT100 graphics mode
    (-Qv, default in Latin-1 terminal) if mined was linked with termcap
    (which is the default on cygwin and some other systems). Linked with
    ncurses, the termcap API would deliver the correct information to
    be handled by mined. This bug (needing such a long explanation)
    exposed only in rare situations, especially on cygwin :(

    With the workaround above, enabled graphic menu borders in more terminals
    (also in CJK terminals).

    PC terminal character set assumed when a PC terminal is detected was
    actually codepage 850, not 437 as previously described. Now it varies,
    according to terminal name. Adapted documentation.

    Abandoned option -G (which displayed some control characters as graphics)
    which didn't work anymore since 2000.8.

    Workaround: explicitly disabling 256 colour mode for KDE "konsole" terminal
    to avoid buggy blinking on using the respective control sequences.

    Fixed position handling of long line with screen display shifted out left
    if left shift marker is enabled. Enabling this feature by default.

    Revised format of MINEDTAB and MINEDSHIFT environment variables for
    more intuitive configuration.

    Fixed the auxiliary scripts "installfonts" and "makeprint" to use
    `pwd` rather than $PWD which is not maintained by all shells.

    Added option -xrm 'UXTerm*locale:false' to scripts umined and uterm in
    order to make sure UTF-8 mode is enforced and prevent xterm (older
    version) from involving luit which would occasionally stall when started.

    Fixed Xdefaults.mined example resources to refer to 9x18U and 10x20U
    rather than 9x18 and 10x20 as those names are used in the Unicode
    X fonts package.

    Fixed wrong screen position handling of indication of illegal CJK
    codes starting with 8E in EUC-JP encoding on CJK terminals.

    When a PC terminal is detected, mined uses the brighter version of
    red for "dimmed" display of line markers instead of the almost
    invisible very dark red.

    Fixed some numeric/mnemonic character input/transformation functions to
    not perform "smart" handling, e.g. TAB expansion to white spaces.

    Fixed HTML tag input to not perform "smart" handling, esp. replacing
    less/greater angles with a double arrow.

    Fixed search for matching MIME separator to really match the actual
    separator and not simply go to the next "--".

    In rxvt, Unicode characters that are Not Assigned are always displayed
    as a single-width replacement character. This is not consistent with
    xterm behaviour which would display them as a double-width replacement
    if they are located within a double-width Unicode range (which sounds
    reasonable). This would cause display positioning inconsistencies.
    Mined now has a workaround for some of these cases (assuming that
    rxvt runs the most recent Unicode width data version available;
    or actually the same as mined assumes - handling of multiple
    auto-detected terminal Unicode versions does not cover this special case).

    Fixed accent prefix keys to always give precedence to the accented
    character rather than the RFC 1345 mnemonic character in ambiguous cases.

    Suppressed inappropriate message "Unknown character mnemonic" when
    a two-letter mnemonic input or control-digit accent prefix input
    is cancelled (with ESC or a function key).

    Fixed inappropriate error message "Unknown mnemonic character" to
    "Invalid character" if a valid two-letter mnemonic is entered but cannot
    be inserted because the current encoding does not support the character
    (this special case had gone wrong with the general fix of this matter
    in 2000.10).

    Fixed positioning error in +V mode (placing the cursor behind the pasted
    region) if the last paste buffer line contained TAB characters. This
    enables making it the default behaviour for the Insert key and
    properly supporting the ring paste buffer by default.

    Tuned menu item for Hebrew quote mark style to avoid right-to-left
    display confusion on bidirectional terminal (mlterm).

    Fixed mnemonic character transformation (ESC _) in non-UTF-8
    mode for non-ASCII mnemonics (like the ones for Vietnamese).

    Added missing character conversion of non-ASCII input in an 8-bit terminal
    for CJK text encoding.

    Printing: If the auxiliary uprint script fails, try to put the fallback
    invocation of lp/lpr into UTF-8 mode, using LC_ALL and hoping that this
    has an effect (maybe with cups properly configured).

    Fixed bogus screen scroll-down on mouse klick in KDE konsole.

    Tuned popup menu handling to always ignore an initial (immediate) mouse
    release event so if the menu happens to pop up right under the cursor
    it does not prematurely select an action.

    Fixed display of "\" character in ESC prompt in Shift-JIS or Johab
    text encoding mode (since 2000.10).

    Fixed display of no-break space on prompt line in CJK terminals.

    Fixed display of some special line indications (e.g. Unicode paragraph
    separator) in various situations (e.g. xterm -cjk_width).

    Removed scrollable pull-down menus from the feature list of 2000.11 as this
    was not (and is not) true. Pull-down menus are cut to the screen height,
    pop-up menus and keyboard mapping selection menus are scrollable.

    Revised toggling of character encoding (by clicking on the Encoding flag)
    which often used to forget its toggling alternative (since 2000.10).

    Fixed environment settings TERM=ansi or ansi-nt to let mined assume
    CP850 terminal encoding (e.g. with Windows command line telnet).

    =============================================================================
    Changes from mined 2000.10 -> mined 2000.11 (July 2005)
    ===========================================

    Interactive enhancements:
    -------------------------
    Conciliated keypad assignment preference conflict between Cut/Paste
    functions (as propagated by mined) and character deletion /
    line positioning functions (as often commonly expected):
    - Additional character deletion function Alt-Del.
    - Better documentation for alternative -k option.
    - Changed error message "Mark not set" to include a hint on keyboard usage:
    "Mark not set for Cut and Paste - type Alt-Del to delete char, F1 k for help".

    Enabled scrolling for popup menus (esp. flag menus) so that menu
    opening in low-height terminals (e.g. 24 lines or lower) is no longer
    suppressed and esp. the Encoding and Input Method menus are always shown.

    Updated to Unicode 4.1.0:
    * Case conversion, Script information.
    * Combining character width properties (continuing to work with older
      width data versions by terminal auto-detection).
    * Updated Han information (from Unihan database) for CJK characters.
    * Updated Radical/Stroke input method to include new CJK characters.
    * Added Hanyu Pinlu and Tang pronunciation information (from Unihan
      database) to Han information options.
    * Added generic and supplemental character input mnemonics for new
      LATIN characters.

    Indication of Unicode combining characters (visible indication and
    character information) now refers to the most recent Unicode version,
    not the actual terminal capabilities; a combining character not handled
    as such by the terminal will be highlighted also in combined display mode.

    Renamed File menu item "Paste file" to "Insert file" (which is probably
    more common usage). So also the menu item "Print" can now be selected
    with a single "p" key.

    Additional assignment of "Delete single" function (to delete without
    auto-undent, or to delete the last combining accent only) to F5 Backarrow
    in case Control-Backarrow is not configured.

    Renamed File menu entry "New Name" to "Save To ..." which is considered
    more intuitive. It changes the file name associated with the edit
    buffer but doesn't save the file yet; the originally loaded file (if
    any) is not affected.

    Additional commands F1 F1 / Shift-F1 / Control-F1 / Alt-F1 to display
    a help line (in the bottom status line) with short indications of the
    functions assigned to the function keys F2... in normal and shifted
    modes. With HOP, permanent display of this help information is toggled.

    Interoperability enhancements:
    ------------------------------
    Accepting xterm resource mode "XTerm*modifyCursorKeys: 3".

    Accepting Alt-function key combinations from terminals that implement
    them by prefixing ESC.
    New option -A to disable this feature and avoid the accompanying delay
    after ESC ESC before mined exits.

    Accepting Alt-function key combinations formed by appending ;11 etc
    instead of ;3 etc after ESC [ or by inserting 11 etc after ESC O.

    Detecting right keypad function key combinations as distinguished from
    small keypad in rxvt in order to better support the various shifted
    Home/End/Delete key combinations (in support of revision mentioned
    under "Interactive enhancements").

    In KDE "konsole" terminal, disabling rounded menu borders by default
    as konsole is lacking decent font support for Unicode characters.
    (Patch included in SuSE 9.3 mined 2000.10 package.)

    Added keyboard configuration examples for Control-function key detection
    for rxvt and mlterm to the runtime support library.

    Replaced function key mappings for "HP workstation keyboard" with
    those for older extended VT100, older xterm, and some others for an
    enhanced range of terminal interoperability.

    Added shifted (Control-/Alt-) function key detection for HP terminals
    or (with xterm) keyboard mode.

    Added function key detection for SCO terminals or (with xterm) keyboard mode,
    including Shift-/Control-/Alt- combinations, plus PuTTY SCO mode shifted keys.

    Added script to support Unicode X font installation to the
    runtime support library.

    Added xterm parameter -mk_width to xterm start script "uterm" for
    UTF-8 mode in addition to -u8 (applied from xterm version 201).
    This enables the xterm built-in most recent version of Unicode width
    data, even if the system-provided locales maintain an older version.

    Provided makefile for Interix. Included function key assignments
    (escape sequences) for Interix console.

    DOS version (djgpp): Unified keypad and function key assignments to
    mined functions with general (Unix) version. Remapped specific
    screen size and mode control functions to Control-/Alt- with +, -, /
    (Control or Alt with +, -, or / keypad key).

    Further enhancements:
    ---------------------
    New TAB expansion option (-+4 or -+8) that expands TAB key input
    to an appropriate number of Space characters.

    Added "smart arrows" input text replacements (in addition to smart dashes)
    if smart quotes mode is active.

    Revised print script (uprint in the runtime support library) to use
    paps (a Pango printing script) if available. Removing temporary file
    after printing.

    The "search corresponding bracket" commands ESC ( or ESC ) now also match
    /* */ pairs and #if #else/#elsif #endif structures.

    Smart text replacements (esp. smart dashes) are suppressed while
    entering multiple characters during a repeat command.

    New case toggle function Shift-F3 cycles casing of a word between
    all small, beginning capital, and all capitals. For Japanese script,
    it toggles the word between Hiragana and Katakana.

    New function key assignments:
    * Alt-F2 to Save to a different file ("Save As")
      (was Control-F2 previously)
    * Control-(Shift-)F2 to enforce creation of the text position memory
      file @mined.mar to ("Save Position", then Save)
    * Control-F3 to View a file (edit read-only)
    * Alt-F7 / Alt-F8 to search backward
    * Control-F10 to open first flag menu (Info menu)

    Added PC DOS encoding ("codepage 437") to available encodings.

    The command ESC _ (or Control-F11) also replaces an HTML character
    tag (e.g. €) with its represented character.

    Packaging, building and installation:
    -------------------------------------
    Moved doc/compilation to COMPILE.DOC so the subdirectory doc of the
    distribution archive now contains only user documentation.

    Added PACKAGE.DOC with hints how to make system-specific mined packages.

    Leaving out the default link src/makefile from the distribution as it
    used to confuse some installers for which the default (GNU make and cc)
    does not work. A generic make with auto-detection of the suitable makefile
    should be invoked from the top-level distribution directory as described
    in the file INSTALL.DOC.

    Bug fixes:
    ----------
    Fixed missing use of terminal capability to "enable alternate
    character set" (terminfo enacs, termcap eA) so graphic menu borders
    should now work in some remaining cases and no longer be replaced with
    letters.
    (Patch included in SuSE 9.3 mined 2000.10 package.)

    Fixed partial scrollbar update logic to prevent gaps in scrollbar display.
    (Patch included in SuSE 9.3 mined 2000.10 package.)

    Tweaked panic handling to terminate more smoothly after a screen output
    error (e.g. if output crashes with ncursesw 5.4 on a more than 3 bytes
    UTF-8 sequence).
    (Patch included in SuSE 9.3 mined 2000.10 package.)

    Suppressed activation of xterm "mouse hilite tracking" mode if compiled
    with curses.
    (Patch included in SuSE 9.3 mined 2000.10 package.)

    Fixed menu border handling with xterm -cjk_width mode, including a
    workaround for xterm font handling bug.

    Emacs command mode (-e): Fixed ^X^C not to unconditionally save file
    but to prompt first (like mined command ESC q).
    Also fixed ^Xk (which previously behaved like ESC q) to edit a new
    file (thus discarding the edit buffer, like F3).

    Fixed part of keymap generation mkkbmap (yudit keymap auxiliary script).

    Fixed character width interworking problem with CJK-encoded rxvt.

    Fixed missing display of menu continuation indication (scrollable
    keyboard mapping pick list) with non-graphic menu borders (option -Qa).

    Fixed recognition of smart quotes style in previous file editing session.

    Limited display of pull-down menus (File menu etc., not flag menus) to
    screen height so that in low-height terminals (less than 22 lines)
    confusing bottom menu item display is avoided when navigating down.

    Fixed incorrect usage of terminal height adjustment (workaround for
    occasional cygwin xterm mismatching xterm / tty size, since 2000.10)
    for window height lower than 24 lines.

    Added error detection and message to command "Save Position" but not
    to implicit save position function when actually writing the file
    as the message would inappropriately interfere with the file writing
    information (and maybe error message referring to this).

    Fixed re-positioning to previous cursor position after opening a file
    when the previous position had been after a combining character.

    Fixed wrong sorting sequence of non-BMP case conversion entries
    leading to case toggle not working for various (also BMP) characters
    (since 2000.4).

    Unified function key assignments of some special keyboards with those
    on usual keyboards (xterm, VT100, ...):
    F6, F7 on Sun and HP keyboards, F10, F11, F12 on Iris keyboards,
    F16-F20 on 9780* keyboards.
    Mapped F13-F22 on 9780* keyboards generically to Control-F3-F12 (may
    be shifted in addition).

    Fixed display of control characters on prompt line in CJK mode; (they
    were incorrectly echoed, and incorrectly handled when erased, in 2000.10).

    Explicit encoding option (-u, -EG, -EW etc) has to override environment
    preference for text encoding (unless for non-CJK encoding in CJK terminal
    which is not supported). Fixed missing overriding.

    Removed remark in manual page (option -E with CJK encoding) that
    UTF-8 auto-detection could override explicit encoding selection which
    is not true anymore since 2000.10.

    Fixed writing of panic file on nested catching of external signals.

    Fixed missing update of window title (file name) in some cases when
    file name was changed for writing but writing was cancelled.

    Fixed selection of usable temporary directory with respect to
    considering its write permissions.

    Fixed flickering multiple update of flags area when starting mined
    (e.g. showing "L1" twice, then "U8") (since 2000.5).

    Fixed smart quotes mode handling to be taken from previous editing
    session when opening a file which did not properly set
    plain style in some cases (since 2000.9).

    =============================================================================
    Changes from mined 2000.9 -> mined 2000.10 (February 2005)
    ==========================================

    Features:
    ---------
    Added radical/stroke lookup input method for CJK characters.

    Added Han character information (Han info option in new Info menu) for
    both text browsing and pick list character selection. This displays
    selectable character pronunciations and descriptions from the Unihan
    database, either on the status line or in a popup menu.

    Poor man's bidi mode was tweaked and enabled by default unless the
    terminal is detected (or configured) to be a bidi terminal; this mode
    enhances inserting small pieces of right-to-left (e.g. as quotations)
    into left-to-right text; when switching from right-to-left back to
    left-to-right by entering a left-to-right character, the cursor
    automatically skips to the end (visual end) of the previously entered
    right-to-left text on the line. This priority is justified by the
    assumption that this mode (with visual storing order) is only useful
    for inserting small right-to-left quotations into left-to-right text
    and not for editing right-to-left documents (which should be stored in
    logical order).

    Many more enhancements and additions for internationalisation and
    character encoding support:
    * Updated character data to Unicode 4.0.1.
    * Combining characters in CJK encodings are now supported.
    * Multiple mapped 8-bit character encodings are available, including
      full combining character support.
    * UTF-16 is handled transparently.
    * For details and further features see below.

    Many enhancements and additions for character input support:
    * CJK, Vietnamese, Thai, Hebrew.
    * Combined character editing in CJK and 8 bit encodings.
    * For details and further features see below.

    New header line command HOP "-" underlines the line that starts before
    the cursor position.

    Added a printing feature that prints the text being edited
    considering the selected text encoding. (It uses a Unicode printing
    script contained in the runtime support library and the uniprint
    program from the yudit package.)
    Modified the item in the File menu to print the file (or actually
    the edit buffer), not the paste buffer.

    The menu interface was enhanced, see below.

    User interface enhancements:
    ----------------------------
    Enhanced menus with subtitles.
    Enhanced flag menus with markers that show which options are activated.

    Made menu items selectable by typing the first letter of their
    descriptions, cycling through all items beginning with that letter.

    Enabled menu item selection by mouse wheel scrolling. Note that your
    mouse driver may be configured to generate multiple (e.g. 3) mouse
    wheel events on one mouse wheel movement (e.g. with Windows).

    Rearranged default input method menu according to the order of the
    letters "CJK".

    Keyboard mapping selection menus ("pick list") that are too large to
    fit on the screen are now scrollable and pageable (with cursor keys).

    Revised navigation in pick lists (keyboard mapping selection menus);
    improved highlighting and function of cursor movement.

    New mode for more stylish menu item selection highlighting (-QQ).
    Looks nice on Unicode terminals. Not made the default, however,
    because block characters used for it might not align well with simple
    borders with all fonts.

    Displaying line-end entered on prompt line (esp. for searching) using
    highlighted marker representation (like for text display) rather than
    control character representation.

    Revised character indications for characters (esp. CJK) that cannot
    be displayed for various reasons; made indications uniform on
    different terminals.

    Command interface enhancements:
    -------------------------------
    ^V followed by a function key now generically invokes the same function
    as with control-function key.

    Enhanced numeric character input with the option of Unicode value
    input in CJK or mapped 8 bit mode by typing a 'u', 'U', or '+' (in
    addition to an optional '#' or '=' for octal or decimal numeric input).

    With numeric character input, the Space key was modified to enable
    "successive multiple character entry" according to ISO 14755; so if
    the numeric code is terminated by a Space key, another numeric
    character can be entered subsequently.

    Added Alt-E command to open encoding menu; modified Alt-V command
    to toggle between view only and edit mode (to reuse previous Alt-E).

    Added Alt-F10 to open first flag menu (info menu).

    Added cedilla accent prefix function to ctrl-F5 (combining this and
    ring above as they are not ambiguous).

    Added Help to eXtra menu.

    Additional command ESC @ to set marker (in addition to control-@ /
    control-Space, ESC ^, control-], or the Home or Select key, for the
    sake of keyboard configurations that cannot easily enter those -
    control-Space may not be configured, ^ may be an accent prefix "dead key",
    control-] may be caught by telnet, Home may be cumbersome on Laptops).

    The "search corresponding bracket" commands ESC ( etc. were extended:
    In case you are editing a mailbox file, these commands also work for
    MIME separators or mail headers; in this case, the search direction
    depends on the command character, e.g. ESC ( searches backward, ESC )
    searches forward.

    Added command Alt-F9 to repeat the previous search but in the opposite
    direction. Added command Alt-Shift-F9 to search for current identifier
    backward.

    Mnemonic input support enhancements:
    ------------------------------------
    Completed mnemonic patterns (generic accent mnemonics) for Latin-based
    characters, supplemented more intuitive patterns for "accents below".
    Completed documentation of these mnemonic patterns and enhanced the
    overview in the manual and on the "Character Mnemos" web page.

    Revised additional character composition mnemonics; made additions
    consistent with generic RFC1345 mnemonics, removed redundant mnemonics,
    added missing Latin characters (esp. with multiple accents).

    Tweaked mnemonic character input handling to allow input of ambiguous
    mnemonics in long mnemonic input mode (e.g. "^V pi " in contrast to
    "^Vpi", where the long form prefers the RFC 1345 mnemonic).
    The ugly previous solution to prepend an additional "1" for ambiguous
    RFC 1345 mnemonics was replaced by this new mechanism.

    Enabled mnemonic character input support (^V Space mnemo Return)
    for non-UTF-8 encodings.

    Input method support enhancements:
    ----------------------------------
    Added two input methods to the default set of preinstalled input methods:
    WuBi (after having read it's perhaps the fastest input method used by
    professional typists in mainland China) and 4 Corner.

    Added generation feature for further keyboard mapping tables
    (used as input methods) for further mappings from Unihan data
    in addition to Cangjie: MainlandTelegraph and TaiwanTelegraph codes,
    pronuncations for Cantonese, HanyuPinlu, Mandarin, Tang,
    JapaneseKun, JapaneseOn, Korean, Vietnamese.
    (Not included in distribution as these seem of questionable value,
    entries included in keymaps.cfg but disabled.)

    Added generation feature for further keyboard mapping tables
    used for Vietnamese input methods: VIQR , VNI , Vtelex.
    Include VIQR and VNI in the default configuration.

    The keyboard mapping generation script mkkbmap inserts additional
    punctuation automatically.

    With the environment variable MINEDKEYMAP, both active and standby
    keyboard mappings can be preselected, e.g. MINEDKEYMAP=py-rs.

    Option +K enables keyboard mappings (input methods) even in 8-bit
    terminal or when editing a Latin-1 file - although the characters thus
    entered will mostly only be displayed by substitute indications, as
    most characters anyway when editing UTF-8, CJK encoded, or mapped
    8 bit encoding files in an 8-bit terminal.

    Keyboard mapping generation from Unihan data (with mkkbmap using mkkmuhan)
    sorts characters in entries according to the priorities of their
    Unicode ranges (assigning lower priority to "Supplement" and
    "Extension" and "Compatibility" ranges).
    This especially affects the Cangjie input method in a few character
    selections. So the "pick lists" are now displayed more in order
    of relevance.

    Further input support enhancements:
    -----------------------------------
    Added Vietnamese accent prefixing method found on the web, using
    control/alt-digit combinations as prefixes. This is only enabled
    when additional key translations for xterm are configured with
    the X resources. (Added to Xdefaults.mined sample file.)

    Added character composition mnemonics (using generic accent prefixes)
    for Vietnamese double-composed characters, i.e. placing a second accent
    on Vietnamese base characters that already have a single composition,
    e.g. if you have mapped your keyboard to have A with circumflex
    available, you can enter "^VÂ'" (Control-V A-circumflex apostrophe) to
    produce the combined character U+1EA4 (A with circumflex and acute).

    Added a Thai input method.

    Added control-backspace function that removes combining accents from
    combined characters and also does not unindent on leading blanks.
    This is only enabled when an additional key translation for xterm is
    configured with the X resources. (Added to Xdefaults.mined sample file.)

    Added Hebrew quote style (using Gershayim U+05F4 for quotation
    and Geresh U+05F3 for apostrophe), and added Hebrew Maqaf (U+05BE)
    as a smart dash replacement for "-" if there is an adjacent Hebrew
    character.

    Character encoding support enhancements:
    ----------------------------------------
    Updated character data to Unicode 4.0.1:
    case conversion, character-to-script mapping, screen width (continuing
    to work with older width data versions by terminal auto-detection).
    Updated keyboard mapping table for Cangjie input method accordingly.

    Combining characters in CJK encodings are now supported
    (both JIS encodings and GB18030), in either UTF-8 or CJK terminal mode.

    Added further 8-bit character encodings, including full combining
    character support.

    Maintaining UTF-16 transparently, i.e. a UTF-16 encoded file is
    written back in UTF-16 again (with BOM) (was previously converted
    to UTF-8). No explicit menu/command line options are currently
    available for UTF-16 as internal handling is in UTF-8.

    Made handling of Unicode LS and PS line ends (previous option -uu)
    the default. New option +u-u disables them.

    The character information command (ESC u) or mode (HOP ESC u) was
    enhanced to conform to ISO 14755; in UTF-8 mode, CJK mode, and
    mapped 8 bit encoding mode, Unicode character information is displayed
    additionally: script name, character category, and Unicode value.

    The Han character information mode always shows the character code,
    and in CJK encoding mode additionally the Unicode value, independently
    of availability of Unihan character descriptive information for the
    current character.

    Added options +C, +CC, +CCC for fine-tuning of display of unknown
    CJK character codes on CJK terminals.

    Added option -CC to assume CJK terminal and override UTF terminal
    auto-detection.

    Revised (fixed/tweaked) character value transformation commands
    [HOP] ESC X/U/D/A to perform a more useful and consistent set of
    functions; HOP ESC X now also scans a UTF-8 sequence; [HOP] ESC U
    now transforms values between current text encoding and Unicode;
    [HOP] ESC D/A now acts like [HOP] ESC U but using decimal/octal.

    Interoperability enhancements:
    ------------------------------
    Improved UTF-8 and CJK terminal feature auto-detection for speed-up on
    slow terminal connections.

    Assuming terminal to run PC character set (codepage 850) if
    environment variable TERM begins with "pcansi", "nansi", "ansi.",
    or contains "-emx", to support remote login from DOS box to Unix.

    Enabled optional PC character set operation when running cygwin version
    in DOS box (when using CYGWIN=codepage:oem in a DOS box).

    Added handling for rxvt-specific cursor and function key escape sequences.

    Revised handling of screen attributes for better and extended support
    of legacy terminals, relying more on termcap and checking if
    direct use of ANSI controls as a fallback is appropriate (usage
    of hard-coded ANSI controls cannot be just avoided because for many
    colour terminals, colour handling is usually not configured with
    termcap/terminfo but of course users want the xterm colour feature to
    be made use of).

    Enabled semi-stand-alone operation of cygwin version (with only
    cygwin1.dll needed to be available, but without installed cygwin
    system, especially without termcap information accessible) by assuming
    hard-coded terminal properties for the "cygwin" terminal if it is
    unknown by the system.

    Enabled menu border option -Qa for DOS version for use with embedded
    dosemu (esp. running in an xterm where it does not emulate DOS block
    graphics characters).

    Enabled menu border option -Qa for curses version, and enabled use
    of Unicode menu borders for curses version.

    Tweaked terminal block graphics capability detection, enabling block
    graphics (rather than ASCII graphics) on more terminals (e.g. cygwin).
    Also using termcap "ac" / terminfo "acsc" capability now to support
    proper block graphics on more terminals (e.g. mac, ibm3151).

    Abolished use of the MINEDTERM variable. Now determining all
    terminal-specific properties and restrictions from TERM.

    Added make target "minced" to build a curses version; it uses
    the ncursesw library which supports UTF-8. Using curses is discouraged,
    however; see the comments in doc/compilation.

    Building and installation enhancements:
    ---------------------------------------
    Added installation of runtime support library (online help, templates
    for inclusion of environment settings and X resources, scripts to
    configure and invoke xterm in a suitable way, printing script, script
    that helps building a printing environment).

    Added make targets "localinstall", "optinstall", and "homeinstall" so
    the user can choose explicitly to install in /opt or $HOME/opt, or in
    either /usr or /usr/local with corresponding different subdirectories
    as used by various systems.

    Revised makefiles to improve building on legacy systems.
    For dynamic make targets / dependencies, introduced dynamic makefile
    generation with non-GNU make. (Maintaining two versions and keeping
    $(shell ) feature with GNU make for less confusing user feedback.)

    Revised directory names used in makefiles for installation of
    mined manual and help files as used by various systems in the
    /usr or /usr/local hierarchies.

    Further enhancements:
    ---------------------
    Added push marker stack before searching for current character (HOP ctrl-F8).

    Improved documentation how to set up a common inter-window paste
    buffer in a heterogeneous network using the environment variables
    $MINEDTMP and $MINEDUSER. Enabled using the same buffer for
    DOS version (djgpp).

    Added environment variables ESCDELAY and MAPDELAY to tune the waiting
    time applied for recognising function keys or input method sequences to
    be mapped, respectively.
    ESCDELAY also affects the time the terminal has to respond to a
    cursor position report request (used for terminal capability detection).

    Added push to marker stack before replace with confirm (ESC r) starts.

    Added command line option ++ to terminate options (to support
    filenames that start with "-" or "+").

    Revised checking and reporting attempts to enter, compose or transform
    character codes or mnemonics that are illegal or not valid in the
    current encoding; e.g. added "Invalid character" feedback when trying
    to insert a character that does not exist in the current encoding.

    Added "o" to the set of numbering items taken into account with
    clever paragraph rewrapping.

    Special handling of Turkish "i" for case toggling is now triggered
    by environment variables LANG or LC_ALL or LC_CTYPE beginning with "tr"
    (rather than the special variable MINEDTURKISH).

    Bug fixes:
    ----------
    Fixed cursor remaining invisible after using a menu in cygwin version.

    Fixed makefile to enable compilation with djgpp again.
    This also fixes a compilation problem with some SunOS configurations.

    Fixed mnemonic character input handling to enable input of ambiguous
    HTML mnemonics starting them with "&" (e.g. "^V ¬ ", broken since
    mined 2000.8).

    Changed separated display mode indication flag from acute to grave to
    avoid interference with ambiguous width property (xterm option
    -cjk_width). Also its background colour was changed from reverse to
    cyan to be consistent with the combining character display itself.

    Disabling fine-grained scrollbar if -cjk_width terminal mode is
    detected to avoid interference with ambiguous width property.

    Constrained usage of "mouse hilite tracking" mode to xterm;
    on some other terminals (esp. cygwin, rxvt) this could interfere with
    a scroll down control sequence and would incorrectly scroll down the
    screen on left mouse clicks (since mined 2000.4).

    Tweaked mkchrtab script (compiling character set mapping tables) to
    work for cygwin in some cases that used to expose weird compiler errors.

    Fixed positioning problem after suppressing second quote mark in
    flags area if first quote mark is a double-width character (used
    to output a NUL character then which produces a space on some terminals,
    e.g. cygwin DOS box - this is now being suppressed).

    Considered to constrain usage of 256 colour mode to "xterm" to avoid
    screen garbage if the mode is not compiled in to rxvt and other
    terminals.
    This applies to scrollbar colours (unless explicitly configured with
    environment variables) and to Unicode script highlighting (by
    lowest-distance mapping of colours to the 8 basic colours).
    (But as screen garbage with buggy rxvt occurs only in some
    configuration modes, 256 colour usage was left enabled there.)

    Fixed GB18030 auto-detection and width handling.

    Fixed EUC-JP half-width character width handling in CJK terminal
    (rxvt in EUC-JP mode). Note that these characters are not displayed
    properly by cxterm in EUC-JP mode.

    Fixed overriding of explicitly selected CJK encoding (e.g. -EG) by
    VISCII auto-detection (since 2000.9).

    Avoid using vt100 graphics for menu borders in rxvt and cygwin xterm which
    do not seem to support them (option -Qv is available to enforce them).

    CJK character codes that do not map to Unicode are now displayed
    with the indication '?' with cyan background to avoid screen garbage by
    invalid character codes, unless overridden by the +C option for
    transparent display of CJK encoded characters.

    Fixed buffer size limitation for search expression ranges not to
    corrupt buffer.

    Fixed interrupted highlighting in selected line of quote style menu in
    8 bit terminals after non-8-bit quote mark replacement indication.

    Fixed error messages on character input support (e.g. mnemonic) to
    be consistent with respect to "Unknown character mnemonic" versus
    "Invalid character".

    Enabled input of NUL character with ^V NUL (^V control-Space).

    Fixed fine scrollbar display which used to mix up top and bottom part
    of marker in some cases.

    Fixed fine scrollbar display which used to leave gaps in some cases of
    adding lines.

    Fixed resolving ambiguous function key control codes with certain
    specific terminals.

    Fixed margin interpretation when setting left or right line margins to
    current position with Enter in a shifted line - using real line column
    now instead of screen column.

    Fixed missing refresh of menu header line after cancelling a keyboard
    mapping pick list by clicking on the encoding or combined display flag.

    Fixed incorrect assumption of combining screen if locale was incorrectly
    configured to indicate UTF-8 in a non-UTF-8 terminal.

    Fixed reverse highlighting problem on some terminals with mnemonic
    character input on prompt line.

    Enabled scrollbar display in djgpp version.

    Fixed function key detection for DOS versions compiled with curses
    which was broken since 2000.7.

    Disabling pipe input/output detection in DOS version when DOSBox is
    detected (by looking at %COMSPEC%).

    Fixed display bug after inserting TAB in CJK-encoded text.

    Fixed inappropriate "conversion" of line-end into U+3000 with
    diacritic transformation command (ESC _) (since 2000.8).

    Workaround to accept delayed cursor position reports instead of
    giving an error message. This affects slow remote connections and
    the cygwin terminal if configured with CYGWIN=tty (in which case the
    cursor report comes only after the first keyboard input which is a
    cygwin bug).

    Fixed generation of script colouring table from colours.cfg which
    could have failed with small-letter script names depending on locale
    environment (since mined 2000.10 alpha as script names were all-caps
    before).

    Fixed ^V__ which didn't input ^_ as documented (since mined 2000.4).

    Tweaked scrollbar attribute handling so that useful scrollbar display
    is enabled in hanterm. This needed a workaround so that the scrollbar
    position is now indicated by blank space in a CJK terminal using
    Korean encoding (UHC or Johab) if TERM=xterm. If you use another
    terminal in this configuration (e.g. cxterm or rxvt with TERM=xterm)
    set the environment variable MINEDSCROLLFG="44;36" or ="38;5;45"
    to reenable coloured display of the scrollbar position.

    Fixed display bug when an incomplete UTF-8 sequence was followed by
    a TAB character.

    Fixed non-ASCII command characters to work regardless of active
    encoding.

    Fixed missing indication for no-break space (U+A0) in UTF-8 mode
    with djgpp-compiled version (was inconsistently shown as blank).

    Fixed one buggy entry in VISCII character mapping.

    Added ASCII remapping entries in Shift-JIS and Johab character mappings,
    and handling them for display and input.

    Tweaked encoding toggle function (when clicking on the character
    encoding flag in the flags area) to properly toggle between the
    current and the previous text encoding.

    Fixed xterm workaround of tweaking window title string (showing the
    filename) for non-ASCII characters in UTF-8 screen mode.

    Fixed Turkish case conversion special handling which was broken since
    2000.4; added further special handling for Turkish and for Lithuanian
    COMBINING DOT ABOVE.

    =============================================================================
    Changes from mined 2000.8 -> mined 2000.9 (March 2004)
    =========================================

    Enhancements in character encoding handling and input support:
    --------------------------------------------------------------
    Used more compact representation for character set tables and
    keyboard mapping (input method) tables, reducing size of binary by > 700K.

    For Japanese encoded text on a UTF-8 terminal, the JIS encodings that
    map to two Unicode characters are supported.

    Keyboard mapping / input methods: Configurable function of space key
    in multiple choice selection menu (option -K).

    Keyboard mapping / input methods: added support for VIM keyboard mapping
    files.

    Tuned CJK encoding auto-detection.
    Tuned CJK vs. ISO 8-bit auto-detection.

    Added VISCII auto-detection.

    Added Shift-JIS auto-detection.

    CJK encodings may be selected (or disabled) to be taken into account
    for auto-detection by configuring the environment variable MINEDDETECT.

    Added option -l for more intuitive selection of Latin-1 text encoding
    (and disabling of auto-detection) rather than with +u.

    Tuned terminal mode auto-detection to reduce flickering delay on 8-bit
    xterm (using fewer test strings) and improve stable fallback if
    auto-detection fails partially on slow terminal connections.

    The keyboard mapping menu can be grouped with separators, specified
    in the keymaps.cfg file.

    Features:
    ---------
    Smart quotes: auto-detection of quotation marks style on file loading.

    Keyboard mapping / input methods: added support for VIM keyboard mapping
    files.

    New functions for interactive character encoding conversion
    (Latin-1 / UTF-8) to partially fix files with mixed encoding:
    A search function finds UTF-8 characters in Latin-1 mode, and vice versa.
    The character can then be converted into the current encoding.
    The search function is invoked with HOP search corresponding -
    e.g. HOP ESC ( - or Alt-F11 .
    The conversion is invoked with the diacritic transformation function,
    e.g. ESC _ or ESC ö , which was extended for this purpose.
    For repeated interactive conversion, both functions can be combined
    with Alt-Shift-F11 (convert current character, then search next).

    Enhancements in user interaction:
    ---------------------------------
    Implemented a finer-grained scrollbar in a UTF-8 terminal, using
    Unicode character cell vertical eighth blocks U+2581..U+2587.
    (Can be disabled with -o1 if font does not contain those characters.)

    Implemented lazy scrollbar update for speed-up on slower
    terminal lines (e.g. remote access). (Can be disabled with -o8.)

    Verified correct recognition and function of mouse wheel movement.
    Scrolling by multiple lines (option -LN, default N=3), or by 1 line
    with control, or by 1 page with shift.

    Added "paste previous" function (emacs style buffer ring) to Edit menu.

    Added backspace capability to decimal number input function (e.g. to
    enter a line number or margin column).

    Tuned position of popup menu not to appear far right of the line contents;
    if clicked there, the menu is placed on the the line end
    (which is the new cursor position in this case).

    The diacritic transformation command (ESC _) derives language-specific
    preferences (such as can be explicitly applied by using the command
    variations ESC ö etc) from the locale environment.

    Added a sample xterm key translation to Xdefaults.mined to assign
    the HOP function to the Scroll Lock and Pause keys in order to
    provide the HOP function easily on Laptops/Notebooks.

    Making cursor invisible while menu is open.

    Revised menu names for CJK encodings for better recognition.

    Further enhancements:
    ---------------------
    Position stack and return function also work across files
    (esp. after identifier definition searches using tags file).

    Added /usr/share/info as a search path location for the online help file
    to meet cygwin conventions, adapted makefile.cygwin installation dirs.

    When editing multiple files, switching to another one resets the
    view only flag to its invocation state (option -v).

    Tuned various file loading functions (including character encoding
    auto-detection) to speed up startup with large files.

    Bug fixes:
    ----------
    Fixed declaration of getenv which caused failure on 64 bit systems.

    Added quotes to egrep parameter in global makefile, needed with some
    shells (would cause make to fail on SunOS).

    Fixed display of non-break space (0xA0) in Latin-1 text and terminal
    mode on prompt line.

    Fixed missing tolerance against multiple blanks separating choices
    in keyboard mapping files.

    Fixed encoding handling problem after toggling from VISCII to UTF-8
    (by clicking on encoding flag).

    Fixed width assumption when inserting certain characters (e.g. Euro sign)
    in GB18030 mode which led to wrong cursor position.

    Fixed a problem with moving between flag menus.

    Fixed a missing screen update problem after replacements with
    embedded newlines.

    Fixed a wrong screen update problem (missing lines near end-of-file
    on screen) after replacements with embedded newlines.

    Fixed corrupted paste buffer after tags file search (for identifier
    definition, ESC t) that spoiled a subsequent paste operation with
    inserted garbage.

    Added auto-detection of terminal capabilities for plane 2 double-width
    and plane 1 / plane 14 combining characters, avoiding display confusion.

    Fixed cursor positioning problem when mouse was clicked during prompt
    line input after menu invocation.

    Fixed cursor positioning bug (since version 2000.8) after character
    insertion on the first screen column in a shifted line (an overlong
    line shifted for display).

    Fixed paragraph justification (line wrap) to use TAB for indentation
    on subsequent lines (instead of blanks) if a numbered paragraph starts
    with a TAB after the numbering (as it used to do with unnumbered
    paragraphs).

    Restricted mode (--) prevents ESC E (switch from view only to edit mode)
    and ESC W (save unconditionally).

    Re-included Turbo-C 2 project file which had been overwritten by
    Turbo-C 3 project file. (Turbo-C is not really recommended anymore
    but as it still compiles, I'm keeping it available.)

    Adapted format of online help files to avoid multiple backspace
    characters for bold formatting which does not work with newer
    versions of less.

    If the editing buffer cannot be filled (out of memory), the associated
    file name is cleared to assure that the file is not accidentally
    overwritten with its truncated buffer version. (This was already
    unlikely because the editing mode was set to View only, but it could
    still be saved with an enforced Save command like Shift-F2 or ESC W.)

    Not displaying the number of characters anymore after loading a file
    with CJK encoding and without predetermined encoding (e.g. loading with
    -C only, or just by auto-detection) because the number used to be wrong.
    The correct character count can be displayed at any time with the ESC ?
    command. Character count after loading is still displayed for Latin-1
    or UTF-8 encoding, or if CJK encoding was explicitly specified (e.g. -EG).

    Fixed bugs in ESC t command (to find declaration of current identifier)
    if tags file search expression contained special characters (tab, \, *).

    Fixed top of marker stack not being recognised as such after marker
    push operations.

    =============================================================================
    Changes from mined 2000.7 -> mined 2000.8 (August 2003)
    =========================================

    Features:
    ---------
    Major extension of CJK character set support: GB18030
    (Unicode-compatible 4-byte extension of GBK),
    extended EUC-JP (including 3-byte encodings),
    and CNS (EUC-TW with 4-byte encodings).

    Added support for mapped single-byte character encodings,
    enabled Vietnamese VISCII character set (option -EV).

    Auto-detection of terminal features (UTF-8, different width data
    versions, handling of double-width, combining and joining characters;
    CJK, handling of non-EUC code points, GB18030, 3-byte and 4-byte encodings).

    Flexible locale configuration for both text and terminal encoding:
    Mined accepts both explicit encoding suffixes (starting with ".") or,
    if none are specified, also some region suffixes (starting with "_").
    See manual page, section "Locale configuration".

    Smart dashes: If smart quotes are active, also an input sequence
    of "--" is replaced with an en dash (if preceded by a blank) or
    an em dash.

    New emacs mode: functions are assigned to control keys and Meta-keys
    (ESC commands) as defined by the emacs editor. Also the emacs paste
    buffer ring and cut/paste behaviour was implemented.
    This mode is in beta state and detailed documentation (esp. command
    listing) is not available yet.
    The mined ESC commands can be reached via Meta-x.
    Function keys remain unaffected.
    See also option +V.

    The multiple buffers ring is also available in non-emacs mode.

    Enhancements in special display of character encoding:
    ------------------------------------------------------
    Enabled display of Unicode FULLWIDTH forms in Latin-1 terminal.

    Enabled substitute display of CJK encodings in Latin-1 terminal,
    with clear display of FULLWIDTH ASCII.

    Enabled substitute display of Euro sign in Latin-1 terminal.

    Alternative options -Eg / -Ej / -Ec to set -EG / -EJ / -EC but
    if running in a CJK terminal this tells mined to assume that the
    terminal cannot display GB18030 4-byte encodings, CNS 4-byte
    encodings, EUC-JP 3-byte encodings, respectively.

    Revision and improvement of CJK display indications:
    ¤  (cyan background) (8-bit terminal): CJK cannot be displayed here
    @  (cyan background) (CJK terminal): CJK code cannot be displayed on terminal
    # (cyan background): invalid CJK code (not assigned in selected encoding)
    # (cyan): illegal (esp. incomplete) CJK code

    The character encoding indication in the flags area was extended to
    two letters.

    Enhancements in character input support:
    ----------------------------------------
    Tweaked handling of character selection menu ("pick list" for
    multiple choice mappings) so that a blank key moves on to the next
    alternative. Also the cursor-right/left keys move within a selection
    line now.

    Added input method TUT.roma for Japanese.
    Revised Hiragana and Katakana input method tables.

    CJK input method tables were extended with punctuation mappings.

    Extended low/capital letter toggle function (F11) to toggle
    between Hiragana and Katakana.

    Enhanced smart quotes heuristics to support smart quotes in CJK text.

    Revised input mnemonics for Unicode accented characters; removed
    redundant mnemonics.

    Additional input mnemonics :(, :), ): for smileys (Unicode mode).

    Diacritic transformation function enhanced with language-specific
    preference transformations:
    control-F11 and ESC _ apply the default transformations
    which are the same as available for two-letter mnemonic input (e.g. ^Vae).
    With Escape commands with diacritic letters that occur on respective
    national keyboards, the according preference transformations take
    precedence:
    ESC ö, ESC ä, ESC ü, ESC ß: ae->ä, oe->ö
    ESC é, ESC è, ESC à, ESC ù, ESC ç: oe->oe ligature (Unicode mode, U+0153)
    ESC æ, ESC å, ESC ø: ae->æ, oe->ø
    ESC _, control-F11: ae->æ, oe->oe ligature (Unicode mode, U+0153)

    Enhancements in command input:
    ------------------------------
    Made Delete/Remove keys on keypads configurable to either Cut or
    Delete character right. The option -k now switches all Home/End
    and Del keys to the more usual behaviour, although I still think
    it's a waste of keypad space to have these functions on two
    keypads; I think the mined approach to leave the standard behaviour
    on the "small keypad" and assign buffer functions to the right-most
    keypad is more useful.
    If the keyboard emits specific control and shift sequences,
    control-Del is always "Delete character right" and shift-Del is
    always "Cut to buffer" in either key assignment mode.
    Also control-Home and control-End always moves to the beginning or
    end of the current line, while shift-Home and shift-End always
    invoke the buffer functions (mark and copy).

    Revision of function key assignment.
    F12 is no longer attached to the diacritic transformation function
    (assignment had been inadvertently overridden for some releases already),
    as on some (many?) terminals F12 cannot be distinguished from shift-F2.
    New function assignments:
    F12	enable memory for file positions in current directory
    F11	(unchanged) low/capital letter toggle
    shift-F11	low/capital toggle for whole word from cursor (like HOP F11)
    control-F11	diacritic transformation, e.g. ae->æ
    ctrl-shift-F11	(like HOP ESC U) transform Unicode value into character
    shift-F2	write file even if unmodified
    control-F2	save file as (prompt for new name, then save)
    shift-F4	write paste buffer to file
    alt-Insert	replace text just pasted with preceding paste buffer
    control-F4	replace text just pasted with preceding paste buffer
    shift-Home	mark position
    shift-End	copy to buffer
    control-Home	go to line beginning
    control-End	go to line end
    Home		(default) mark position
    End		(default) copy to buffer
    Home		(with -k option) go to line beginning
    End		(with -k option) go to line end
    Home/End	(on small left keypad) reverse function of right Home/End
    HOP shift-F8	search for definition of current identifier (using tags file)
    HOP control-shift-F8 search for identifier definition (prompts)
    HOP control-F8	search for current character (new function)
    VT100: Find	search
    VT100: Select	mark position
    VT100: Do	copy to buffer
    control-Up	(new, see below) move to previous paragraph beginning
    control-Down	(new, see below) move to next paragraph beginning
    control-Ins	copy to buffer
    control-@ (control-space) mark position

    New commands to move to previous/next paragraph boundary:
    control-Up, control-Down (hold control key and press cursor up or down).

    The current text position is pushed on the position stack also with
    the Goto Line/% command (^G).

    Enhancements in terminal operation:
    -----------------------------------
    Tweaked screen attribute handling to improve behaviour of certain
    terminals that do not match their termcap entry (esp. cxterm).

    Tweaked screen handling for menu borders to provide workarounds
    for various weird terminal behaviours (esp. mlterm and linux console).

    Moved some ambiguous function key escape sequences into a special
    table that is (automatically) only selected if a vt100 terminal
    is set up (by the TERM variable). Added assignments for shifted
    function keys of certain terminal emulators.

    Further Enhancements:
    ---------------------
    When a menu is open, the cursor-left or cursor-right keys cycle
    through the pull-down and flag menus.

    Added smart quotes style for Japanese corner brackets.

    Smart quotes style can also be preselected with the environment
    variable MINEDQUOTES which should then contain the opening/closing
    quote pair or just the opening quote mark.

    Renamed X resource configuration plug-in .Xdefaults.mined to
    Xdefaults.mined for better handling and to comply with other
    packages' usage.

    Enhanced the script to generate man pages from HTML to handle tables.
    Fixed manual page generation to filter out empty lines which spoiled
    the layout.

    Manual:
    * Added discussion of the disputed keypad function assignment into Key
      layout section.
    * Moved HOP section right behind the Key layout section.

    Options:
    --------
    New option -* to disable mouse support (requested by an emacs mode
    user who prefers to use the xterm copy/paste mouse function).

    Option +V to enable emacs-style paste buffer functions for "delete
    word" and "delete to end of line" commands (^T, ^K), and place the
    cursor behind the pasted region after buffer insertion.
    (May become the default in a future version, disabled by -V.)

    New option -QX to select the style of menu borders where X is one of
    	s: simple border,
    	r: rounded corners,
    	f: fat border,
    	d: double border,
    	a: ASCII border (can be combined with another option -Qs or -Qr),
    	v: VT100 alternate character set graphics border,
    	@: reverse blank border.
    Mined sets an appropriate default based on its assumptions of the
    terminal capabilities.

    Latin-1 or UTF-8 character encoding can now also be selected with
    the -E option: -EL, -EU.

    Bug fixes in CJK handling:
    --------------------------
    Removed length restriction on keyboard mapping multiple choice
    menu, thus enabling Pinyin input method to work.

    Fixed mnemonic character input problem in CJK mode.

    Fixed handling of unmapped Unicode characters in CJK terminal mode
    in input method selection menu, avoiding ragged menu borders
    (but leaving empty entries for menu consistency between encodings).

    Bug fixes with paragraph justification:
    ---------------------------------------
    Fixed paragraph justification on lines with two successive blanks
    (as used after a sentence by some people) which could actually wrap
    lines between the blanks (and leave leading blank on the next line)
    if the right margin happened to be at that point.

    Fixed clever paragraph justification on lines without blanks which
    used to change the right margin.

    Fixed a display handling bug that could lead to wrong display after
    invoking paragraph justification from the menu.

    Bug fixes with screen display:
    ------------------------------
    Fixed interference of Unicode line end display (-uu) with
    paragraph end display (-p).

    Fixed menu width handling (esp. when HOP was entered in an open
    flags or popup menu near the right screen border) which could wrap the
    menu display around the screen.

    Further bug fixes:
    ------------------
    Fixed missing resp. overridden recognition of Alt-Enter in some
    situations (used for jumping in the cursor position stack).

    Fixed handling of keyboard mapping selection menu in right-to-left
    terminal (e.g. mlterm) near the end of text which could crash mined.

    Tweaked ESC D and ESC A commands to insert decimal resp. octal value
    of whole character, not of separate encoding bytes. Behaviour is now
    as it was already documented.

    Fixed HOP ESC U command which (by the HOP prefix) inserted a pair
    of parentheses if invoked on the code of an open parenthesis.

    Fixed inadvertent setting of restricted mode on "-" options prefix
    (since version 2000.7).

    A function key entered on the prompt line does no longer abort
    prompting but just beeps.

    Fixed explicit cursor marking in proportional terminal mode in
    CJK text mode.

    =============================================================================
    Changes from mined 2000.6 -> mined 2000.7 (May 2003)
    =========================================

    Features:
    ---------
    Enhanced support for character input methods, especially for
    East Asian (CJK) character ranges; selection menu for keyboard
    mapping choices ("pick list").
    Pre-compile-time configuration of additional mappings is provided,
    usual mapping tables of other editors can be used as source.

    Support for editing files in different CJK encodings, also in a
    UTF-8 terminal. The apparently major encodings in use are supported:
    Big5 (with HKSCS), GBK (> GB2312, EUC-CN), UHC (> EUC-KR), EUC-JP.
    These are tried to auto-detect by heuristic counting of character codes.
    An option to select the encoding (-EX) or auto-detection are also provided.
    Two more encodings supported but not auto-detected are Japanese
    Shift-JIS encoding (including single-byte mappings to Halfwidth Forms)
    and Korean Johab character set and encoding.

    Enhancements:
    -------------
    Added flag menus to all flags (except HOP indication) for more
    intuitive usage.

    Enabled repeat function with keyboard mapped characters.

    Enabled hex entry of CJK double-byte characters on prompt line in
    CJK mode (-C).

    Enabled decimal (in addition to hexadecimal or octal) coded character
    input.

    Tweaked script to generate keyboard mapping table from yudit keyboard
    mapping file: strip final blank if contained in all entries, skip
    intermediate dummy blank.

    Enhanced UTF-8 auto-detection so that longer UTF-8 sequences are
    not ignored.

    Flag indication for combined/separated display mode (of Unicode
    combined characters) was tweaked to make it more intuitive.

    Added "+", "-" and various Unicode bullet characters as numbering
    items for clever justification (triggering indentation).

    Activated colour usage for line markers and scrollbar in CJK terminals
    (newer versions of hanterm apparently support colour).

    In CJK terminals, mapping line markers from Unicode values according
    to effective encoding table, so hopefully matching the right
    CJK character for marker display.

    Revised CJK special character input support, fixed illegal character
    handling problems with coded CJK input (also on prompt line).

    Revised handling of incomplete CJK half character codes. Don't pad
    them with blank on loading the file anymore.

    Revised character counting while loading the file to work with CJK
    and auto detection.

    Option +G to enforce using block graphics characters for menu borders
    is now accepted in CJK terminals as newer versions support them.

    Makefile for Mac OS X (provided by Tobias Ernst).

    Bug fixes:
    ----------
    Fixed a bug that would display control characters (e.g. ^X) entered
    directly on the prompt line in UTF-8 mode as letter X with coloured
    background instead of ^X.

    Revised character input thoroughly; fixed deficiencies (since 2000.6
    even crashes, shame on me) if the repeat function was provided with a
    non-ASCII character.

    Fixed handling of invalid hex CJK double-byte character insertion.

    Fixed undefined insertion of arbitrary character if character insertion
    from character code in text (HOP ESC U/D/O) didn't recognize a number.

    Fixed insertion of partial character bytes when an open menu was
    cancelled by typing a Unicode character.

    Fixed failed recognition of bullet character (0xB7) in non-Unicode mode
    as a numbering item for clever justification (triggering indentation).

    Removed those RFC 1345 input mnemonics mapping to private use code points;
    fixed some of them to map to valid code points.

    Removed -D option; this feature (which did not work in UTF-8 mode anyway)
    may now be achieved with a keyboard mapping if desired.

    Fixed erroneous special handling of 0xA0 (as no-break space) in CJK mode.

    =============================================================================
    Changes from mined 2000.5 -> mined 2000.6 (Feb 2003)
    =========================================

    Features:
    ---------
    Arabic ligature joining support:
    If the terminal supports right-to-left display (e.g. mlterm)
    mined assumes that the terminal also applies automatic joining of
    Arabic ligatures (LAM/ALEF combinations).
    Mined supports ligature joining by accounting for the screen position
    accordingly, and by indicating the joining part of the ligature in
    separated display mode similarly to the handling of combining characters.
    This terminal handling mode is configured with the option +UU.

    New command ESC Return (Alt-Return) to "return to previous position".
    On commands that jump away from the current position (HOP Mark,
    File Begin/End, Search, Search Idf definition), the current position
    is remembered in a position stack. The new command ESC Return goes
    backward, HOP ESC Return forward in this "stack".

    Added recognition of mouse wheel control sequences and attached
    according behaviour - untested as I don't have a mouse wheel.

    Enhancements:
    -------------
    New key interpretations for shift-Return (shift-Enter) and
    control-Return (control-Enter) to insert Unicode paragraph separators
    and line separators respectively if Unicode line-end handling is enabled.

    Improved prompting for hex/octal character input, made more intuitive.

    Improved coded character entry on prompt line: added visual feedback,
    added octal option, enabled for non-UTF-8 mode.

    Improved mnemonic character entry on prompt line: added visual feedback.

    Implicit suppressing of keyboard mapping during mnemonic character input.

    Enabled mouse release and movement support in DOS version (DJGCC).

    On opening a file, the current position marker is no longer initially
    set to the opening position (as some users got confused with the
    Cut/Paste function); to return to the position e.g. after searching,
    use the new command ESC Return instead of HOP Mark.

    Options:
    --------
    The option -c selects separate display mode on UTF-8 terminals. The
    mode can also be toggled from the eXtra menu or on the C/c flag
    next to the U/L character encoding flag.
    The previous option to assume that the UTF-8 terminal that does not
    support combining characters was changed to -cc.

    Bidi terminal mode is selected explicitly with +UU instead of
    implicitly (by disabling the scrollbar with -o).

    Additional option -8 to set TAB size to 8 (to override TAB size
    being set to 4 by MINED environment variable).

    Changed option -J (to set justification level 2 initially) to +jj.

    Added option +U to configure UTF-8 terminal operation. This is
    in order to allow defined setting in addition to -U which toggles
    the pre-configured assumption and might turn out to produce the
    wrong assumption.
    Changed -U to also set combining mode when assuming UTF-8 mode.
    Note, however, that none of these options needs to be used if the
    environment is correctly configured to indicate UTF-8 as it should
    (LC_ALL, LC_CTYPE, or LANG ending on ".UTF-8" or ".utf8").

    Added option +UU to configure bidi terminal operation. This mode
    implies UTF-8 and also assumes that Arabic ligature joining
    (of LAM/ALEF combinations) is applied.

    Bug fixes:
    ----------
    Display problems in separated display mode (for Unicode combined
    characters) on the status line were fixed, including Arabic joining
    ligatures.

    When deleting the last accent in a Unicode combined character (after
    moving the cursor position into the character), the display was not
    updated; this was fixed.

    Fixed documentation of some vt100 keypad key assignments (original
    assignments were mangled by Linux console keypad assignments).

    Fixed F5/control-F5/shift-F5 and according F6 accent composition
    prefixes and adapted documentation.

    Mentioned shift-F2, shift/control/control-shift-F8, shift-F9, shift-F10
    in documentation.

    Fixed ^O new line insertion: if the line is terminated with a Unicode
    paragraph separator, a line separator is used for the new line end.

    Fixed and adapted behaviour of HOP Return to insert Unicode paragraph
    separator.

    Revised character set handling for PC versions; revised accented
    character composition;
    accented character display and composition (from 8-bit character range)
    now working in PC versions for either PC or UTF-8 character encoding.

    Fixed status line update problem after operations on parts of combined
    characters (e.g. movement onto the combining accent with ^V cursor-right).

    Fixed character composition from text [ ESC_ ] to consider characters,
    not bytes.

    Search corresponding bracket [ ESC( ] now also works with UTF-8
    multi-byte characters.

    Fixed identifier search [ HOP F8 ] to work with UTF-8 characters
    inside identifier.

    Included sources for online help in the distribution archive as
    needed for "make install".

    Fixed a crash problem with window resize, then display being redrawed,
    then resize again and output being interrupted. Occurred under rare
    and unclear conditions; now ignored.

    Fixed makefile.bsd for NetBSD.

    Added top level makefile, selecting OS-specific makefile automatically.

    =============================================================================
    Changes from mined 2000.4 -> mined 2000.5 (Dec 2002)
    =========================================

    Feature: Keyboard mapping
    -------------------------
    Keyboard mapping for various scripts is available in UTF-8 mode
    (both edited text and terminal must run UTF-8).
    This maps keyboard input characters or short character sequences to
    characters (or short sequences) in a different script.
    In this release, mappings for Greek, Cyrillic, Arabic, and Hebrew have
    been integrated.
    An active and a standby keyboard mapping are maintained. They can be
    toggled quickly for text input with ESC k (or Alt-k), also on the prompt
    line (e.g. for searching).
    Command overview:
      ESC k toggles between active and standby keyboard mapping
    	also on prompt line
      HOP ESC k resets keyboard mapping to none (unmapped input)
      ESC K opens the keyboard mapping menu
    	also on prompt line
      HOP ESC K cycles through available keyboard mappings

    Note: As some typical keyboard mappings contain ambigous key sequences
    where one may be a prefix of another, a short delay is applied in
    these cases to allow recognition of any such sequence to be mapped.

    The current mapping is indicated by its two-letter script tag in the
    flags area (top screen line), clicking on it cycles through the
    available mappings (like HOP ESC K), clicking with the right button
    opens the Keyboard Mapping menu (like ESC K).

    With the environment variable MINEDKEYMAP the active or standby
    mapping can be preselected. The value is a two-letter script tag to
    set the active mapping, or it is prepended with "-" to set the
    standby mapping.
    Example: export MINEDKEYMAP=-gr will set Greek keyboard mapping standby.
    Known script tags are:
      ar -> Arabic
      gr -> Greek
      el -> Greek
      he -> Hebrew
      cy -> Cyrillic
      ru -> Cyrillic

    Options and further features
    ----------------------------
    Bidirectional terminal support:
    To run mined on a bidirectional terminal (such as mlterm), disable the
    scrollbar with the option -o.
    In this mode, when displaying a menu, underlying text lines that
    contain right-to-left characters are cleared first in order to prevent
    display confusion between the terminal's bidi algorithm and the menu
    position.

    Mined's "poor man's bidirectional support" (which automatically places
    right-to-left characters to the left of the previous character) was
    disabled by default in order to support mined's operation with
    bidirectional terminals.

    Script colouring:
    For better recognition of letters that belong to a certain script
    (where similar looking letters may belong to other scripts),
    text display uses colours to distinguish letters of various scripts.
    This is preconfigured for Greek and Cyrillic (which share some letter
    forms with Latin).
    Compile-time configuration of further script colouring is available
    with the file colours.cfg; it contains entries with the script name
    (as listed in the Unicode data file Scripts.txt), white space, and
    a colour index into the xterm 256-colour mode.

    Two "flag menus" were introduced:
    * one for the Keyboard Mapping (as described above),
    * the other for Smart Quotes selection; it's popped up with the right
      mouse button on the smart quotes indication in the flags area;
      additional commands:
      ESC Q or Alt-Q: also pops up the Smart Quotes menu
      HOP ESC Q: cycles through available Smart Quotes

    When a pull-down menu is opened with the middle mouse button, the
    HOP version of its items is preselected (can be toggled with middle
    mouse button as before).

    -X disables display of the filename in the window title bar.

    Changed default of -G option (enabling display of control characters
    as block graphics) to be disabled.

    Flag indications were slightly tweaked in order to make them more
    intuitive.

    Bug fixes:
    ----------
    Fixed a rare bug with ESC u on illegal UTF-8 characters.

    Clever justification now also considers the bullet sign as a
    numbering (list item) character.

    Back-TAB was tweaked not to apply directly below non-space text of the
    previous line.

    Fixed some bugs and inconsistent results with shortcuts for
    composed character input.
    Added composed character sequences for single-accented extended
    Latin characters.
    Extended diacritic transformation function (ESC _) to all
    two-letter composed characters as configured for input support.

    =============================================================================
    Changes from mined 2000.3 -> mined 2000.4 (Sep 2002)
    =========================================

    Interface:
    ----------
    Made use of advanced xterm mouse tracking modes.
    * Text select and copy with highlighting by mouse dragging.
    * Menu item browsing by mouse dragging.
      If the mouse button is kept down, items are automatically selected
      as the mouse is dragged over them.
      An item is selected by either clicking the left button or
      releasing the left or right button.
      It is also still possible to open and change menus with click-release,
      then select an item with another click (less finger-strain).

    A "non-break space" (character value A0 hex) is now displayed by a
    tiny middle dot (as used for TAB indication) in cyan colour.

    Syntax highlighting
    * Also toggled for .sgml files (as well as for .html/.htm, .xml, .jsp).
    * Extended to JSP and HTML comments.

    In order to avoid command confusion on slow remote connections where
    escape sequences might come in deferred, the following commands were
    changed:
    * Disabled ESC N cmd which repeated the command N times when N
      has only 1 digit (in that case the command might have been a
      function key escape sequence).
      Use ESC = N cmd instead, or use 2 or more digit repeat counts,
      e.g. ESC 77- (to enter 77 '-' characters) or ESC 07x (to enter 'xxxxxxx').
    * Changed ESC O which inserted the octal value of the current character.
      Use ESC A instead.

    When inserting an HTML marker on the prompt line (commands ESC H,
    HOP ESC H) HTML tag attributes can be included; they are only inserted
    for the starting marker, not for the closing marker.

    The TAB width can be toggled between 8 and 4 while mined is running
    (command ESC T).

    Function keys of some terminals (esp. HP and Siemens) are ambiguous;
    the preferred key set to be detected can now be configured
    (environment variable MINEDTERM= xterm / hp / siemens).

    The ESC u command displays additional Unicode script information.

    The parentheses matching commands ESC ), ESC (, etc, now also match
    HTML tags.

    The character compose and input support function was revised.
    Accent prefix functions were extended to support Unicode.
    Additional mnemos were enabled, including TeX and HTML mnemos.

    Features:
    ---------
    Clever justification (auto-indentation):
    With the justification command ESC j, clever auto-indentation is applied.
    It uses heuristic detection of numbered items and program source comments.
    (The old justification function that only considers configured margins
    is available by ESC J.)

    A Back Tab function was added. A Backspace from a position that is
    only preceded by white space on the line will revert the input position
    to the previous matching indentation level.

    In both justification modes, automatic suppression of auto-indent
    applies by heuristic detection of the speed at which characters
    are entered. This is to allow unmodified pasting of text (using
    e.g. xterm mouse copy/paste).

    Checkout and checkin functions for version management systems added
    (to File menu, command scripts "co" and "ci" must exist in path).

    Introduced generic handling of shift state indication for function key
    escape sequences (control/shift/alt and combinations).
    No more "Unknown command" errors on unregistered function key variants.
    By default they invoke the same function as the unshifted key.

    The location of mined buffers can be configured with an additional
    environment variable MINEDTMP ([SYS$]MINEDTMP on VMS). This supports
    copy and paste operations among different machines.

    Bug fixes:
    ----------
    Revised case conversion and other Unicode character property handling.
    Updated tables for wide and combining characters to new Unicode data.

    Fixed some display bugs:
    - Current line was cleared after prompt was aborted with mouse button.
    - Search/replace including linefeeds could mess up the screen.
    - Screen line could mess up on an incomplete UTF-8 sequence at the end
      of a line in UTF-8 text and screen mode.

    Fixed a bug with automatic line-wrap after entering space.

    Fixed some terminal size detection problems after rlogin from DOS.

    Under weird circumstances, the first empty line in a file not edited as
    the first one could produce display and buffer garbage on SunOS.

    Fixed some search pattern match bugs:
    - with empty lines
    - with replace and ^, starting in middle of a line (started replacement
      at that position, not at start of next line)
    - with ^, searching backwards (did not find in current line)

    Removed restriction of regular expressions with Unicode characters:
    search patterns ä* etc (UTF-8: Ã¤*, â‚¬* etc) do work now.

    Manual hints and clarifications:
    --------------------------------
    A search pattern [pat]* matches a (zero or more times) repetition of
    this pattern. In a final position within the search expression,
    however, it matches one or more times this pattern.

    Hex input code ^V # xxxx [space or RET]:
    Works on the prompt line only in Unicode mode, exactly 4 hex digits
    are accepted but are not echoed on the screen.

    Improved description of special character input support in the manual.
    Added overview chapter on input support.

    =============================================================================
    Changes from mined 2000.2 -> mined 2000.3 (May 2001)
    =========================================

    Documentation:
    --------------
    The manual page was updated and thoroughly revised.
    Its primary source was transformed into HTML, roff/man format being
    generated.

    The mined web pages were updated and revised.

    The file "doc/compilation" (with compilation hints) was updated.

    Features:
    ---------
    HOP '/' enters an indented Javadoc comment frame.

    Interface:
    ----------
    Options can be concatenated on the command line.
    (mined -uu instead of mined -u -u enables Unicode line separators.)

    Right-to-left script input support is now enabled by default.
    The option -b toggles it.

    Option -G disables (actually toggles) the display of certain control
    characters as block graphics characters (enabled by default).

    Option +G enforces use of block graphics for display of menu borders.
    May be used if the "alternative character set" capability is not
    configured in your system but your terminal does have the capability.

    Set output delay (-d0..-d9) to none (-d-) by default in all versions.

    The help command was unified on Unix and DOS versions. Not completely,
    however, as calling a sub-programm ("less") through the "system" call
    doesn't seem to work on DOS (it crashes or blocks terminal input
    afterwards, even with cygwin). See also next comment.

    A second help viewing mode is now avaible (HOP HELP, e.g. HOP F1). It
    displays help information within mined itself, restoring the previous
    editing state afterwards.
    This is the default on MSDOS for the reason mentioned before.

    Bug fixes:
    ----------
    Fixed a screen-related pointer confusion after replacement with multiple
    lines (embedded newline) which could result in a display bug and page down
    could be blocked.

    (Very minor) Just deleting the trailing line-end of a file is also
    considered a modification (a file only modified this way would
    previously not have been saved automatically).

    (Minor) With UTF-8 auto-detection involved, the character count after
    reading the file could be wrong (ESC ? would have been correct).

    (Minor) The pop-up menu, when modified with HOP and thus becoming smaller,
    used to leave the frame of its previous width on the screen.

    (Embarassing) Although I was proud of "perfect responsiveness to
    window size changes" I had just forgotten to implement that for
    the case of a menu being open.

    On DOS, editing a file with Unix line-ends, the function "append to buffer"
    used to append the lines with MSDOS line-ends.

    =============================================================================
    Changes from mined 2000.1 -> mined 2000.2
    =========================================

    Features:
    ---------
    Auto indentation when entering a new line.
    Insert a new line without auto indentation with the ^O command.
    Auto indent mode may be toggled from the Extra menu.

    Entering auto-indented pairs of parentheses:
    With the HOP prefix, the characters "(", "[", "{", "<" enter
    an auto-indented pair of "{" ... "}" etc.

    Search and replace patterns can use an embedded newline. Enter
    with ^V ^J. In some cases there are still display problems.
    Then update the screen with the ESC "." command.

    Interface:
    ----------
    HTML files (ending on .html, .htm, .xml, .jsp) trigger a display mode
    which distinguishes HTML tags by coloured display.
    The mode can be toggled from the Extra menu.
    	While you edit within a line and change its HTML ending status
    	(by entering or deleting '<' or '>'), the display status of
    	subsequent lines is not changed. (You may refresh the display
    	with ESC ".")

    Special markers (on cyan background) for illegal UTF-8 sequences are
    applied in UTF-8 terminal mode as well (instead of the Unicode
    replacement character).

    The online help file format and help invocation were changed.

    Online help contents was enhanced.

    Bug fixes:
    ----------
    For relevant file close operations, the return code of close() is now
    checked. Usually, write errors are already noted by write() calls but
    for a few rare cases, this check is appropriate.

    Some display bugs (especially with UTF-8) were fixed.

    Graphic display for menu borders on the Linux console was fixed (funny
    it uses the DOS character set as an "alternative character set").

    Porting:
    --------
    Flexible selection of DOS versions available, all with mouse support.
    (djgpp, cygwin, EMX, Turbo-C).

    =============================================================================
    Changes from mined 2000 -> mined 2000.1
    =======================================

    Features:
    ---------
    Configurable automatic smart quotes (" character on input replaced
    by typographic quote marks depending on style setting, in UTF-8 text mode).

    Completed combined character support, removed some bugs.

    Unicode case toggle handles context-dependent mappings (Greek sigma).

    Interface:
    ----------
    Mined looks for its online help file at certain typical locations so
    it may find it even if MINEDHELPFILE is not configured.

    License:
    --------
    For distribution purposes, the GNU license was imposed, but commented in
    README.

    =============================================================================
    Changes from mined 98 -> mined 2000
    ===================================

    Features:
    ---------
    Scrollbar display
    May be used for relative or absolute positioning with the three mouse
    buttons.

    Flexible and simultaneous handling of different line ends
    Unix and MSDOS line ends can be handled in the same editing session and
    are indicated by different coloured line-end symbols. Files without
    trailing line-end can be edited and created.

    Transparent long line handling
    Overly long lines are now read in transparently. They are attached a "NONE"
    line-end type so they will be written out exactly as they came in.
    Splitting within UTF-8 sequences is avoided; splitting of combined
    characters is not avoided, however, they will join seemlessly as lines
    are joined again. (Combining characters at the beginning of a line are
    not displayed in combined display mode.)

    Special line-end handling details and binary transparency
    With the above two modifications, a couple of line end handling features
    were introduced and binary transparency was achieved.
    * Input of NUL characters from file is accepted and is presented as a
      special "NUL" line-end type. Explicitly entering a NUL character
      works, too (either literally or with ^V # 0). Thus mined achieves
      binary transparency through an editing cycle now.
    * The ^O command in a line with "NUL" or "NONE" line-end will
      reproduce this line-end type in contrast to entering a new-line
      which will always produce a real line-end.
    * In order to split a line in two, separated with "NONE" line-end, use
      HOP ^O (e.g. ^G^O).

    Mac line-end handling
    Mac line ends (CR only) can be transparently read and handled with the
    command line option +R (while -R would transform them into Unix line ends).

    Tags file support
    Moving to the definition of an identifier using the tags file
    (generated by the ctags command) was added. If a new file is opened
    for this purpose, the current file is saved automatically.
    * Command: ESC t when cursor is on identifier (with HOP, it prompts for
      the identifier), or from Search or Popup menu.

    Search and replace enhancements
    Finally, typical Unix tool limitations of line orientation is being
    removed. Mined can search for expressions with embedded new-lines
    (enter with ^V ^J or \n). - Not yet fully implemented! -

    Additional HTML tag input support
    The command ESC H (not ESC h!) now inserts an HTML tag which is
    entered in dialog. Another ESC H inserts the corresponding closing tag.
    * So, continuous entering of HTML contents was made easier.
    * The previous function to embed the text between marked position and
      current position in an HTML tag is available with an additional HOP,
      e.g. ^G ESC H.

    File handling consistency improved
    The command ESC # to edit the nth file from the command line was
    extended with ESC # # which just reloads the current file.

    Remembering editing information between sessions
    In addition to the current position, also the paragraph justification
    margins (wrap-around margins) are remembered until the next
    invocation, but only if justification mode is switched on.

    Tab size can be adjusted to 4 (instead of 8) with the command line
    option -4.

    Keypad assignment to the "Home" and "End" keys can be changed with the
    option -k. Normally, these keys perform the "Mark" and "Yank"("Copy")
    functions. Some people strongly expect these keys to go to the
    beginning or end of line although that really is a waste of key
    assignment as these functions are easily performed with HOP left/right -
    anyway, the option -k exchanges the assignment. The other functions
    are accessible with shift-Home/shift-End (if the keys emit different
    sequences, see X configuration hints).

    Unicode handling features:
    --------------------------
    Combined character display
    Handling of Unicode combined character display is enabled by default
    with UTF-8 terminal operation. (May be disabled by environment
    variable utf8_no_combining_screen, or command line option -c.)
    * There are two editing modes for combined characters: combined and
      separated. Switch modes by clicking on the "c/C" indicator next to
      the UTF-8 "L/U" indicator in the flags area of the top line, or in
      the eXtra menu.
    * In combined display mode, the following special functions are available:
      The cursor can be moved into a combined character with
      ctrl-left-arrow or ctrl-right-arrow, provided these cursor keys are
      configured to emit distinguished escape sequences with control-key
      held. ^V-left-arrow and ^V-right-arrow also work. You can determine
      the exact position of the cursor if permanent character info is
      switched on (by HOP ESC u or with HOP in the eXtra menu).
    * Partially editing combined characters:
      * If the cursor is on a combined character, delete next character
        will delete the whole combined character, with all combining accents.
      * If the cursor is within a combined character, delete next
        character will delete the current combining accent only.
      * In separated display mode, all cursor and text modification
        operations work on the combining parts as displayed.

    Search expressions
    The restriction that search ranges could not be used for non-ASCII
    characters in UTF mode was removed.
    * Search ranges can, however, not be very large as all included
      characters are listed in an internal buffer which is limited to ca.
      1 KB.

    Case toggle
    The character or word case switch function (e.g. in the eXtra menu, or
    F11) works also with all Unicode characters.

    Unicode line ends
    Line separator and paragraph separator are optionally detected and handled.
    * Activate this mode by two -u options ("-u -u" on command line or
      "uu" in MINED environment variable).
    * Inserting a new line on a line with Unicode lineend will insert a
      line separator unless the hop flag is active in which case a
      paragraph separator will be used.

    Basic input support for right-to-left scripts
    After entering a right-to-left character, the cursor position is moved
    left of it, so subsequent characters will be appended left and the
    text shifted right. Characters are stored in visual order while input
    support is implicit, based on the characters being typed. Entering
    left-to-right characters will obviously automatically switch
    direction; to continue with right-to-left, the cursor must be moved
    manually (e.g. to the line beginning).
    * Newline, Space, TAB, and combining characters attempt to behave well
      according to what was entered before; however, intermediate cursor
      movement is not considered.
    * Activate right-to-left support with the command line option -b.
    * This mode is not meant to work with the latest right-to-left xterm
      patch - it would rather interfere with it. The mined right-to-left
      mode is just intended to provide a simple mechanism to quickly enter
      visually correct right-to-left text in a conventional environment.
    * Orientation of text alignment remains on the left side in this mode.
      Suggestions for improvement in order to make it useful for
      right-to-left or bidirectional writing are welcome.

    Interface:
    ----------
    Menu display
    Uses block graphics characters if determined to be available.

    Menu layout
    The pulldown and popup menus are in variable width now (depending on
    contents).

    HOP toggle in menus
    While a menu is open, any of the HOP key, ^G, Blank, or the middle
    mouse button toggles the HOP amplifier and the menu redisplays with
    function names changed where applicable.

    Mouse usage
    Was enabled with curses operation (useful for EMX, see below).

    Keyboard availability of menus
    Menus are available from the keyboard; Alt-letter (or ESC-letter)
    pulls down a menu starting with that letter, Alt-TAB pulls down the
    file menu, Alt-blank pops up the quick menu.
    (In order to make Alt work as a modifier, set the xterm resource
    metaSendsEscape to true as suggested in the example file .Xdefaults.mined.)

    Line begin/end keys, hop key assignment
    In order to get rid of the waste of keyboard assignments which is imposed
    by terminal emulation emitting the same escape sequences for keys of
    the two keypad areas, some X resource definitions were included
    in the file .Xdefaults.mined as a recommendation (section
    XTerm*VT100.Translations). Also the hop key may have to be made available
    explicitly with some X setups (also included in that file).

    Keyboard reassignments
    In order to make room for the Alt-keys to address menus, some
    commands had to be reassigned:
    substitute:	ESC , (was: ESC s)
    set marker n:	ESC m (was: ESC ,)
    screen smaller:	ESC % (was: ESC m)
    screen bigger:	ESC & (was: ESC M)
    case toggle:	ESC C (was: ESC f)
    edit other file: use F3, or "Open" from the File menu (was: ESC e)
    print buffer:	use "print buffer" from the File menu (was: ESC p)

    Operation in system environment:
    --------------------------------
    Window resize propagated to parent shell
    If the window is resized, the SIGWINCH signal is propagated to the parent
    process so that e.g. the shell also knows about the changed size.

    Porting:
    --------
    Windows ports
    Adaptations to enable compilation in Cygwin and EMX environments.
    Works in EMX with ncurses and mouse enabled.

    Windows port with mouse / DOS port?
    A lot of changes to the curses adaptation enabled seemless operation
    in the EMX environment under Windows.
    Unfortunately, EMX does not keep its promise to generate dual-mode
    Windows and DOS executables. Can anyone help?

    Bug fixes:
    ----------
    Searching
    Fixed a few pattern matching bugs (some had slipped in while
    introducing UTF-8).

    Search/Replace
    Fixed start of replacing to current position (instead of line beginning).

    Search/Replace
    Fixed a display bug when replacing was aborted with "line too long"
    outside the current screen.

    Word-wrap
    Paragraph justification moved to the wrong position if triggered by a
    space entered at the end of line.

    Chinese mode display
    In 8/16 bit character set mode, some situations (illegal 16-bit codes)
    of display garbage were fixed.

    Various minor bugs

    ...

    =============================================================================
    Changes from release 5 -> mined release 6 (1995)
    ================================================

    -	Additional word-wrap version:
    	In order to remain a pure text editor (without placing text
    	processing control codes into the text), mined uses trailing
    	blanks as indicators that a paragraph continues. However,
    	sometimes text should be formatted that does not follow this
    	convention. So there is another adjustment option now which
    	terminates formatting a paragraph at the next empty (or blank-
    	only) line.
    -	Optionally remembering the position where you last left a
    	modified file. Automatic re-positioning in next edit session.
    -	Help can now be viewed with mined itself (HOP ESC h).
    -	Increased portability: Mined now compiles on more platforms
    	without changes (HP-UX, AIX, recent SINIX versions).

    =============================================================================
    Changes from release 4 -> mined release 5
    =========================================

    -	The command ESC H to insert HTML commands.
    -	Separate left margins for first and next lines of paragraph.
    -	Startup search expression on command line.
    -	Wild cards in file names on MSDOS.
    -	Can switch between edit and view only modes.
    -	MSDOS version: Beep modified to use the BIOS beep which is
    	redirected by some "beep enhancement" drivers (newbeep /
    	nusound) instead of the DOS beep which for some peculiar
    	reason they don't change.
    -	Compiles on SunOS5.
    -	Sets window headline and icon text to current filename in
    	xterm or sun-cmd window.
    -	Parameter -x to make a new file executable (Unix) in order to
    	create a shell script.
    -	Leading "~" notation for referring to home directory accepted
    	in all filenames.

    =============================================================================
    Changes from release 2 (August 1992) -> release 3 (August 1993)
    ===============================================================

    Main new features:
    -	Paragraph reformatting with left and right margin settings.
    -	Optional WordStar-compatible keyboard layout.
    -	Optional support of 16-Bit character sets.
    	(Works well with the Chinese xterm, cxterm.)

    Some more new or enhanced features:
    -	Screen display was modified to build from the new cursor position
    	(after a search often in the center of the screen) up and down to
    	the upper and lower borders of the screen. This appears to more
    	naturally suggest to the users where they are.
    -	Support for proportional screen fonts was added.
    -	The MSDOS function key sequences were activated in the Unix version
    	as well to enable using Unix mined remotely from a PC keyboard.
    	PC terminal support includes video mode changing as far as it
    	can be performed by escape sequences to the ANSI driver.
    -	Mostly unified option environment into one variable, MINED.
    -	Options for conversion between different line end types.
    -	Extended the enter-control-code prefix (^V) to compose characters
    	if the first following key resembles an accent mark ("'`^°~).
    -	A search for identifier at current position function was introduced.
    -	A repeat previous search (one before the last search) function was
    	introduced.

    Improvements in the MSDOS version:
    -	Improved memory management (problem: the 640 KB memory restriction
    	being effective if compiled with Turbo-C).
    -	MSDOS mined now detects screen size changes on each keystroke, so
    	it reacts almost immediately, e.g., on font changes performed by
    	the VGAMAX font substitution TSR.
    -	Several MSDOS screen mode switching functions were integrated to
    	enable explicit mode change with a command.

    Bugs removed:
    -	Display garbage in very small windows (less than 28 columns).
    		There may still occur display garbage if the window is
    		narrower than the tab size (8 displayable characters).
    -	Display garbage in very long lines.
    -	Display and position bug related with tab characters and long lines.
    -	Display garbage after substitution that made a line shorter so it
    		gets completely shifted out of the left display border.
    -	Incorrect display after aborted substitution.
    -	Aborted substitution although there was enough room on the line.
    -	If the environment variable NoCtrlSQ or NoControlSQ is set, also
    	the tty channel soft handshake setting will not be disabled in case
    	this would affect remote connection behaviour. I had discovered that
    	characters were actually lost on a remote (internet) login connection.

    Keyboard assignment mofications:
    -	Line replace function assigned to ESC R.
    -	Double assigned some functions in support of optional WordStar mode.
    -	Option to adapt Backspace and Delete keys to other convention.

    =============================================================================
    Changes from release 1 (July 1992) -> release 2 (August 1992)
    =============================================================

    Minor changes of behaviour
    -	Control characters can now be searched for.

    Source improvements
    -	Improved portability according to mail feedback.
    -	Compiles without warnings with gcc -ansi -pedantic and
    	various other checks.

    MSDOS version
    -	Compatibility with different ANSI drivers was improved.
    	Runs well with the very capable NNANSI (Tom Almy) or the
    	small and simple well-working ANSI.COM (Michael J. Mefford).
    -	Workaround for problem with Turbo-C libraries that inhibited
    	mined from working in arbitrary size screens ("extended text modes"
    	like 132x44 etc).
    -	The change working directory command now works with respect to
    	different drives, including change of drive only.
    -	Shell escape now available on MSDOS.
    -	A display bug on the prompt line of the search/replace commands
    	was removed (The initial prompt vanished after the first input).
    -	Options can be given starting with / in addition to - .
