! 14: /*
! 15: * Vim originated from Stevie version 3.6 (Fish disk 217) by GRWalter (Fred)
! 16: * It has been changed beyond recognition since then.
! 17: *
! 18: * All the remarks about older versions have been removed, they are not very
! 19: * interesting. Differences between version 3.0 and 4.0 can be found in
! 20: * "../doc/vim_40.txt".
! 21: *
! 22: * Changes between version 4.1 and 4.2:
! 23: * - Included ctags version 1.3.
! 24: * - Included xxd.c version 1.4 (only one change since 1.3m)
! 25: * - Unix: Adjusted check for child finished again. Now use != ECHILD
! 26: * instead of == EINTR.
! 27: * - Fixed: loading compressed files (with autocommands) didn't work when
! 28: * 'textmode' was previously set.
! 29: * - Fixed: When executing a shell, a window resize was not recognized for
! 30: * Unix.
! 31: * - Fixed: For GUI, when executing an external command, a window resize
! 32: * caused the buffer to be redrawn.
! 33: * - Fixed: Error message for not being able to open the .viminfo file could
! 34: * report the wrong filename.
! 35: * - MS-DOS, Win32, OS/2: When $HOME is not set, use "C:/".
! 36: * - OS/2: Improved handling of wildcards again. Didn't ignore case, didn't
! 37: * work with backslashes.
! 38: * - Fixed: ":s/pat<Tab>" could cause a core dump or other problems.
! 39: * - Fixed: When entering a hidden buffer with ":e", the BufEnter autocommands
! 40: * were not executed.
! 41: * - Fixed: Ignoring a CTRL-Z at end-of-file was only done on MS-DOS. Now it
! 42: * also works on other systems, but only in textmode.
! 43: * - Fixed: In the GUI special characters were not passed on to external
! 44: * commands, typeahead was truncated.
! 45: * - Added "gq" as an alias to "Q". Should be used when "Q" is made to be Vi
! 46: * compatible: go to Ex mode.
! 47: * - Fixed: "gu" in Visual mode could not be redone with "." correctly.
! 48: * - Fixed: ":normal" command made any typeahead executed right away, causing
! 49: * unpredictable problems.
! 50: * - Fixed: ":normal atest^[" didn't update the screen.
! 51: * - Fixed: Redoing blockwise visual delete at the end of the file could cause
! 52: * "invalid line number" errors.
! 53: * - Fixed: vim_rename() didn't open the output file in binary mode, could
! 54: * cause the .viminfo file to contain CR-LF on OS/2.
! 55: * - Fixed: OS/2 was using /tmp/xxx for temporary file name, would fail if
! 56: * there is no /tmp directory. Now use $TMP/xxx, defaulting to c:/ if $TMP
! 57: * is not set.
! 58: * - Fixed: When USE_TMPNAM was defined, was using the wrong array size for
! 59: * the viminfo temporary file.
! 60: *
! 61: * Changes between version 4.0 and 4.1:
! 62: *
! 63: * - Included xxd.c version 1.3m.
! 64: * - Included ctags version 1.2.
! 65: * - Included tools/efm_filt.er.
! 66: * - Included changes for port to Atari MiNT, including makefile.mint.
! 67: * - Included a few changes for OS/2: Improved executing external commands,
! 68: * depending on the shell; Handle resize after executing an external
! 69: * command; Handle wildcard expansion for more than one argument (e.g.
! 70: * ":n *.c *.h").
! 71: * - Include a lot of small changes to the docs.
! 72: * - Fixed: GUI version would busy-loop and mappings didn't work. Was caused
! 73: * by gui_mch_wait_for_chars() not working properly. This fix was the main
! 74: * reason for releasing 4.1.
! 75: * - Fixed: setting 'term' while GUI is active was possible, and caused
! 76: * problems.
! 77: * - Fixed: When the "to" part of a mapping or menu command was long (more
! 78: * than 24 chars on 32 bit MS-DOS, 128 chars on other systems), any <> were
! 79: * not translated and CTRL-Vs not removed.
! 80: * - Fixed: 'modified' option was included for ":mkvimrc", it shouldn't.
! 81: * - Included a few changes for that Atari MiNT port (vt52 builtin term
! 82: * entry).
! 83: * - Fixed: on MS-DOS a file name pattern for an autocommand that contains
! 84: * "\*" or "\?" didn't work.
! 85: * - On MS-DOS and Amiga, ignore case when matching the file name pattern for
! 86: * autocommands.
! 87: * - Fixed: using :set to show the value of two options gave an error message
! 88: * (e.g. ":set so sj").
! 89: * - Fixed: Non-printable characters in a file name caused trouble when
! 90: * displayed in a status line.
! 91: * - Pack the MS-DOS zip files with Infozip, under Unix. Preserves the long
! 92: * filenames and case. Files with two dots don't work though, the first dot
! 93: * is replaced with an underscore.
! 94: * - Fixed: Pasting more than one line with the mouse in insert mode, didn't
! 95: * put the cursor after the last pasted character.
! 96: * - When pasting linewise text, put the '] mark on the last character of the
! 97: * last line, instead of the first character of the last line.
! 98: * - Fixed: on some Unix systems, when resizing the window while in a external
! 99: * command (e.g., ":!cat"), Vim would stop waiting for the child, causing
! 100: * trouble, because the child is still running.
! 101: * - Fixed: resizing the window while executing an external command, and
! 102: * 't_ti' and 't_te' are defined to swap display buffers, Vim would redraw
! 103: * in the wrong display buffer after the "hit RETURN" message.
! 104: * - Fixed: "va", "vA", "Vp", "VP", "Vs" and "VS" didn't set the cursor
! 105: * position used for up/down movements (e.g., when using "j" after them).
! 106: * - Fixed: in GUI version, after using "cw" visual selection by dragging the
! 107: * mouse didn't work.
! 108: * - Fixed: setting 'ttyscroll' to 0 caused scrolling of message to stop
! 109: * working.
! 110: * - Fixed: the "WARNING: file changed" message caused buffers to be flushed
! 111: * and subsequent commands not to be executed.
! 112: * - Fixed: in Insert mode, the message from "^O^G" would be
! 113: * overwritten by the mode message if 'showmode' set.
! 114: * - Fixed: Using ":bdel" when there is only one buffer with two windows,
! 115: * could cause a crash.
! 116: * - Changed: the '<' flag in 'cpoptions' now only switches off the
! 117: * recognizing of the <> form of key codes. The 'k' flag is now used for
! 118: * the recognizing of raw key codes.
! 119: * - Fixed: Typing ':' at the --more-- prompt, when displaying autocommands,
! 120: * caused extra linefeeds to be produced.
! 121: * - Fixed: Using 'tagrelative' and ":set tags=./../tags", filenames would
! 122: * contain "../" as many times as CTRL-] would be used. These are removed
! 123: * now.
! 124: * - Fixed: Extremely long error message could cause a crash (e.g., when
! 125: * using ":help ^A<CR>").
! 126: * - Added check for negative value of 'textwidth'.
! 127: * - Fixed: On MS-DOS, getting the value of $HOME would cause the current
! 128: * directory for the drive to be changed.
