Changes from the previous version:
Changes for vile 9.6 (released Thu Dec 27 2007)
> Tom Dickey:
+ update makefile.blc, adding charsets.c, eightbit.c and wcwidth.c
+ build-fix for OS/2 IBM CSet (define a delay function for catnap).
+ minor build-fixes for VMS:
+ modify vmsbuild.com to simplify workaround for broken MMS 3.8
+ provide dummy variables for xvile to reflect modularization changes
with respect to vmsvt.c
+ documentation updates.
+ minor fix to manfilt.c to pass-through UTF-8 codes by testing with
both iswprint() and isprint().
20071224 (u)
> Tom Dickey:
+ separate vile's ttputc from termcap prototype to pass integer param
rather than just a char on Solaris.
+ fix computation of columns needed to show UTF-8 codes in POSIX
locale.
+ modify manfilt.c to provide UTF-8 output in a UTF-8 locale.
+ minor fix to CF_FUNC_ICONV to link iconv on cygwin (noting that
cygwin has no useful locale support, it may someday).
20071202 (t)
> Tom Dickey:
+ modify filters makefile "clean" rule to accommodate OSF/1 4.0D
whose make program leaves intermediate ".c" files for each lexer.
+ change order of restore-flags and switch-buffer in
restore_buffer_state, avoiding an unnecessary prompt to discard
changes when attempting to read a buffer that cannot be read.
+ increase a few table sizes to work with AIX 5.1 lex.
+ modify check for lex version to avoid hanging on older platforms
where it would try to read from standard input even if it does not
recognize the option.

> Tom Dickey:
+ several changes to provide usable Unicode support:
+ add mode percent-utf8 to set a threshold for file-encoding mode
"auto" detection of UTF-16/UTF-32 files.
+ file-encoding mode can be set to "auto", to detect UTF-16 files,
which are loaded as UTF-8.
+ UTF-8 files are detected based on the file-encoding mode as well.
+ Unicode values are displayed (where no locale controls) as "\uXXXX"
in 4 hexadecimal digits.
+ add unicode-as-hex mode to override locale, forcing Unicode values
to display as "\uXXXX".
+ for buffers with UTF-8 encoding, show illegal bytes as "\?XX".
+ Unicode values can be inserted into buffers using ^VuXXXX form.
Limitations:
+ terminal drivers support Unicode display in varying degrees:
+ winvile - multicolumn characters, depends on font selection
+ termcap/terminfo - relies on terminal emulator, knows about
multicolumn characters
+ xvile - displays only single-column characters
+ curses - depends on the curses library, e.g., ncursesw
+ win32 console - not yet implemented
+ combining characters are not combined.
+ registers hold byte data, will show the UTF-8 encoding for data
rather than a \uXXXX (unless the file-encoding for [Registers]
is changed).
+ some "characters" such as the report for yanked text is still
really a byte-count.
+ inserting a \uXXXX into the minibuffer will display the UTF-8
encoding.
+ regular expressions are not wide-character aware.
+ UTF-16 and UTF-32 files are detected based on BOM and/or the
contents of the first line of the file.
+ external syntax filters do not handle BOM or UTF-16, UTF-32.
+ improve name-completion by saving/restoring the original window and
buffer when [Completions] closes, rather than the closest window.
+ add output from rcshist to diffmode.
+ add ".vbp" files to inimode.
+ modify configure script to omit lex-filt.l from build if lex is not
really flex, since the tables are too large for the older program.
+ modify spell.pm to use a temporary file to work with newer Perl's
that do not handle tied variables exactly as filehandles.
+ update Kevin Buettner's email address.
+ add -class option to xvile.
+ remove a redundant XtDestroyWidget() from x_close() to quiet a
warning from XtRemoveGrab() when doing a ":q" from Xm-vile
(report by Chris Green).
+ use va_copy() in dofmt() to work with Linux on powerpc
(report by Paul van Tilburg).
+ add docbookmode
+ improve 9.5m/9.5q check for file ownership, adding a warning message
for files which are ignored (report by Chris Green).
+ change default for --with-locale configure option to mesh with
--disable-extensions.
+ improve paste-performance in winvile by passing whole-line chunks
to the insert-function.
+ improved cppmode's identifier-expr (report by Gerry Fredette).
+ correct order of evaluation from 9.4w when setting record-separator,
which was setting "crlf" ending temporarily when computing the buffer
size, even when "lf" was intended. That would cause an immediate
write from winvile (without change) for a buffer to write too many
characters.
+ add syntax filter conffilt.l, for "ordinary" config-files.
+ add "rectangle-insert-mode".
+ fill in several omitted items in init_mode_value().
+ add "describe-&functions" and "describe-$variables" commands.
(The latter is a stub for later).
+ improve repainting in winvile while processing external command.
also modify keyboard handling to provide type-ahead while processing
external command.
+ remove obsolete $tpause variable.
+ modify majormode inferencing to check preamble for [Standard Input]
and [Output] buffers.
+ add ">motion" function for scripts.
+ improve handling of enumerated values by forcing all to lowercase,
e.g., to eliminate the need for the special case in 9.1x to handle
"TRUE" and "true".
+ revise lstrinsert() and associated logic which implements changes
to rectangles, e.g., with c^Aq, to ensure that it pads the change
with blanks rather than nulls (report by Paul van Tilburg).
+ improve modeline support by ignoring strict "vi" modeline options
that are not recognized by vile, rather than reporting an error.
+ use new module blist (binary search of lists) to reduce linear
searches in the places where btree is not already used.
+ change rename-other-buffer command to other-buffer-rename, to avoid
name-completion conflict with rename-command (feedback from Steve
Lembark).
+ remove obsolete check for ANSI qsort.
+ improve vilefilt.l, highlighting mode names and displaying error
for unknown mode, function and state variables.
+ fix typo in manpage.rc which broke use of pod2man in 9.5m
+ add &pquote in manpage.rc, to allow it to format html output when
vile-manfilt, etc., reside in directories containing spaces in their
name.
+ add ".reg" filetypes to inimode.
+ add several package-related suffixes to sqlmode.
+ add xpmmode
