 pkgsrc changes:
 share distinfo and patch with editor/vile
 XXXX: Should also share Makefile and PLIST.
 
 Changes from 9.5 to 9.5r:
 
  20070603 (r)
 	+ amend makefile.in change for $(SRC) to use a translation rule that
 	  works with IRIX64 (and some broken BSD) make programs.
 	+ correct parsing/removal of "-i" option in winvile, taking into
 	  account double-quoting of parameters and also options which have
 	  parameters.
 	+ make configure --with-no-leaks work for external filters, e.g., using
 	  valgrind.
 	+ add configure script check for tdelete(), provide a replacement if
 	  not found (report by Gary Jennejohn).
 
  20070528 (q)
 	+ change configure script to check for ispell before aspell; Fedora 5's
 	  problem with aspell was eventually fixed.
 	+ make cursor-adjustment after paste in xvile dependent on whether the
 	  pasted text ended with a newline (request by Eric Krohn).
 	+ cleanup the bottom line on the screen when exiting the curses driver,
 	  to match the termcap/terminfo driver (report by Chris Green).
 	+ fixes for pl-filt.c (perl highlighter):
 	  + allow blanks before tag for here-document, e.g.,
 		cat << 'TAG'
 	  + allow '~' as a quote-delimiter (this is used by linklint).
 	+ modify CF_IMAKE_CFLAGS to work with Solaris sed, which (unlike a
 	  standard UNIX implementation) does not honor nested subexpressions.
 	+ add rename-other-buffer command, use that to modify spell.rc so it
 	  can work with scratch buffers which otherwise would be lost, e.g.,
 	  "[Help]".
 	+ add modelines for winvile.rc and w32ole.rc to set the majormode to
 	  rcmode, and modify a special case in main.c to make "vile winvile.rc"
 	  get the corresponding majormode.
 	+ add some null-pointer checks in filters for result from flt_alloc().
 	+ add a check in flt_alloc() in case the pointer has not been
 	  allocated.
 	+ derive $(SRC) from $(OBJ) in makefile.in, to avoid losing trace.c
 	  in tags rule.
 	+ check for empty/default "put" in line.c's PutChar() to avoid
 	  attempting to remove a trailing newline from that, since the
 	  corresponding line has already been freed as part of the undo process
 	  (report by Paul Fox).
 	+ use O_NONBLOCK if O_NDELAY is undefined, needed for a few platforms
 	  which have the POSIX definition but not the legacy, e.g., Minix and
 	  OS X.
 	+ make autocolor work for curses-driver, e.g., --with-screen=ncurses
 	  (report by Chris Green).
 	+ widen the check for "winvile" in vileinit's initialization for win32
 	  shifted cursor bind-key's.
 	+ modify spell filter so that it can get VILE_SPELL_FILT from the
 	  registry on win32.
 	+ improve spell filter camelcasing that when parsing things like
 	  "UXTerm" it splits off the "Term" as a possible word.
 	+ amend 9.5m change to check for file ownership to ensure this is
 	  only done for files that might be source'd.  It was checking files
 	  for read/write too.
 	+ correct syntax highlighting for end of JavaScript embedded in HTML,
 	  which did not allow for the marker in an inline comment.
  	+ modify "filename" shown in :show-filtermsgs to use the buffer name
 	  if no filename is available.
 	+ modify preamble patterns for shell modes such as awk, etc., to allow
 	  for programs without an absolute pathname, e.g., "#! awk".
 	+ modify the symbol-table lookup in filters.c to use tsearch() when
 	  available.  For an 8Mb rtf file this improved performance by about
 	  a factor of two (on Linux - Visual C++ has no tsearch).
 	+ add configure check for getc_unlocked(), putc_unlocked() and
 	  tsearch() to use in performance improvements for syntax filters.
 	+ add syntax filter for RTF files.
 	+ improve autocolor on win32 by not allowing the cursor to be repainted
 	  while autocoloring is in progress.
 	+ modify winvile's command-line parsing, adding "-i" option to perform
 	  the case used for "Send To": use the part of the command line after
 	  options as the filename and change working directory to match
 	  (request by Larry Gensch).
 
  20070425 (p)
 	> Tom Dickey:
 	+ modify spell- and txt-filters to allow users to add words to their
 	  respective ".keywords" files to override the builtin highlighting.
 	+ correct check of return of ffread() in spellflt.l's workaround for
 	  platforms such as win32 which have no usable popen().  That made
 	  spelling checks require two ^X-i presses.
 	+ modify spellflt.l to chop words according to Camel-case, so
 	  tokens such as "ChopWords" are treated by the spell checker as
 	  multiple words.
 	+ fix a limit check in argc/argv[] parsing for winvile (report by
 	  Larry Gensch).
 	+ modify wvwrap.exe to work with pathnames containing "$", "&" and "'".
 	+ change OPT_MULTIBYTE definition to depend on OPT_LOCALE.
 
  20070115 (o)
 	> Tom Dickey:
 	+ change Inno Setup script to not put version numbers on the SendTo
 	  and context-menu entries.
 	+ start adding support for UTF-8 (modes "byteorder-mark" and
 	  "file-encoding").  The byteorder-mark is workable, but the
 	  file-encoding is a stub.  This works to strip the BOM from files
 	  as they are loaded, making syntax highlighting work for XML files.
 	+ correct two places in exec.c which used skip_blanks() rather than
 	  skip_space_tab() from 9.5l changes.  This caused the command
 	  parser to treat ^K as a blank, breaking digraph.rc which uses
 	  that character (report by Gary Jennejohn).
 
  20070108 (n)
 	> Tom Dickey:
 	+ add a character-class check to find_b_file() to prevent names such
 	  as "<vile.1>" from being canonicalized into "vile.1" on win32 via
 	  FindFirstFile().  This fixes a problem where ^X-n would sometimes
 	  display the wrong buffer.
 	+ add shifted-cursor-key bindings for winvile, like xterm.
 	+ amend cursor-tokens mode so that ^X-e in a directory-buffer always
 	  uses the whole line (no regular expressions).
 	+ fix a null-pointer dereference in the cursor-tokens mode.
 	+ minor fix to sh-filt.l to handle lines like
 		: ${BUILD_CC:='${CC}'}
 	+ improve iss-flt.l to highlight preprocessor lines.
 	+ improve winvile.iss (Inno Setup):
 	  + use values in patchlev.h to set the package version information.
 	  + add context menu and Send To shortcuts
 	  + install the keyword files
 	+ add configure --with-valgrind option.
 
  20061212 (m)
 	> Tom Dickey:
 	+ add showvariables mode, for testing expressions used in [Variables].
 	+ correct comparisons used for handling bounds in regular expressions,
 	  e.g., the "2" in "\(this\|[l-m]\)\{2\}".
 	+ change behavior of regular expression OR'd alternatives - only the
 	  first match was used rather than the longest one.
 	+ fix configure script macros which omitted X_EXTRA_LIBS in one case,
 	  and repeated libs in another.
 	+ fill in complete list of event names for xres.key from Xt/TMParse.c
 	+ make ShowFormatted macro more configurable by allowing environment
 	  variables $VILE_NROFF_FILT and $VILE_TABLE_FILT to override the
 	  choice of programs therein.
 	+ disallow source'ing from the current directory if the source'd file
 	  might be writable by other users.
 	+ improve fences in vbs- and vbmode.
 	+ fix xresfilt.l; X resource files do not have embedded comments.
 	+ minor improvements/fixes to &default, to allow it to assume that
 	  '$' is implied for modes.
 	+ modify locale initialization to work with koi8rxterm.
 	+ add character classes [:ident:], [:octal:] and [:path:], and change
 	  the association of \w and \W to [:ident:], making [:alnum:] no longer
 	  include "_".
 	+ add cursor-tokens mode to control whether vile uses regular
 	  expressions, character classes or a combination to obtain tokens
 	  from the screen.
 	+ add $buf-fname-expr to show the combined bufname-expr, pathname-expr
 	  used to interpret ^X-e.
 	+ add bufname-expr, identifier-expr and pathname-expr buffer modes to
 	  provide regular expression parsing of $bufname, $identifier and
 	  $pathname in the show-variables command as well as for the related
 	  expansion of tokens from the cursor position.  If the expressions are
 	  empty, the code falls through to use the corresponding older
 	  character-class parsing.  Default values are provided for each *-expr
 	  mode.
 	+ fix a case where set-window might remove the only window before
 	  attempting to put a file in it.
 	+ quote "$HOME" in CF_SUBDIR_PATH, for cygwin users.
 
  20061107 (l)
 	> Tom Dickey:
 	+ modify ":describe-bindings" to show whether the command accepts a
 	  range, and whether it is undoable.
 	+ add ":goto-percent" function.
 	+ add (nvi/vim) ex-commands: a!, c!, i!
 	+ add ":c" as alias for ":change-til" (nvi/vim).
 	+ change unimplemented ":c" to ":co" (reference O'Reilly vi-book)
 	+ fix makefile dependency for tags
 	+ review/update use of "CNT" in describe-bindings
 	+ revised command-line option parsing to use scripting more effectively:
 	  + multiple startup files are allowed.
 	  + most command-line options are translated to their equivalent script
 	    and executed, rather than saving state for the most recent of each
 	    option.  This makes the -s, -S, -g, -G options obsolete (but still
 	    accepted).
 	  + add "-c" option (the POSIX form of "+").
 	+ modify configure script to use ncurses5-config, etc., if found when
 	  handling the --with-screen=ncurses or --with-screen=ncursesw options.
 	  It also is checked when handling the --with-ncurses option for the
 	  termcap/terminfo driver.
 	+ add suffix/name rules for "Jam" files.
 	+ fix preamble pattern for pymode so it does not match a ":" line
 	  which should be shmode.
 	+ implement patterns as line-specifiers in ex-mode.
 	  (this does not work with history-scrolling yet).
 	+ remove incorrect check for empty parameter from which-menu from 9.4m
 	  changes.
 	+ check xvile menu to ensure that "C" header is given, adding a
 	  dummy one if not (report by Chris Green).
 	+ add checks to ensure that neither modelines nor majormodes can alter
 	  these modes: all, crypt, readonly, viewonly.
 	+ implement vi-style modeline, limited to setting buffer- and window-
 	  modes, or majormodes.
 	+ add "#" as an alias for number-lines-til
 	+ improve highlighting of comment-lines (denoted by "--") in txtmode.
 	+ fixes for termcap syntax highlighter (tcmode):
 	  + allow description field to be empty
 	  + color the "|" between aliases.
 	  + improve string- and escape-parsing
 	+ fixes for terminfo syntax highlighter (timode):
 	  + allow description field to be empty
 	  + color the "|" between aliases.
 	  + allow aliases to contain blanks.
 
  20060924 (k)
 	> Paul van Tilburg
 	+ add syntax filter (mcrl) for mCRL/mCRL2 modeling language.
 	> Tom Dickey:
 	+ modify fileread() to ensure that the error-buffer is reset after
 	  reading (or re-reading) a shell/pipe command, e.g., using ":e!".
 	+ fix configure --disable-largefile option (from ncurses).
 	+ minor fixes for nroff filter to improve rendition of groff's macros.
 	+ add configure check for ncurses 5.2(sic) on FreeBSD, which was broken
 	  by an incomplete set of changes to wchar.h (report by Chris Green).
 	+ add configure check for aspell, whose attempt at a compatibility
 	  script for ispell does not recognize ispell's options.
 	+ workaround for breakage in FreeBSD's header files: updates to wchar.h
 	  were not reflected in updates to curses.h (report by Chris Green).
 	+ remove reference to obsolete http://www.vile.cx from README (report
 	  by Paul Fox).
 	+ update config.guess, config.sub
 
  20060625 (j)
 	> Tom Dickey:
 	+ fix expression for shmode $mode-filename to match ".profile".
 	+ various small build-fixes (prompted by reports by Paul Fox, Clark
 	  Morgan).
 	+ amend 20050214 change to set_files_to_edit(), which caused partly-
 	  read buffer to be discarded if ffgetline() was interrupted, e.g.,
 	  by a ^C during a slow pipe read.  Now the buffer contents are
 	  retained.
 	+ update config.guess, config.sub
 
  20060531 (i)
 	> Tom Dickey:
 	+ fix error-reporting for a "~break" without a preceding "~while"
 	  (report by Clark Morgan).
 	+ minor fixes for tc-filt.l (termcap mode).
 	+ fix x11.c for Motif broken in 9.5f cleanup (reported by Paul Fox).
 	+ improve bas-filt.l by not highlighting incidental matches in the
 	  attribute section of a Visual Basic form-file.
 	+ correct parsing of hexadecimal constants in bas-filt.l
 	+ add .ctl suffix for vbmode
 	+ fix a case in bsizes() which subtracted line-ending from zero-sized
 	  buffer when nonewline mode was set (Debian #368007).
 
  20060521 (h)
 	> Clark Morgan:
 	+ document write-all-buffers command.
 	+ add echo-to-clipboard mode for Win32 hosts:
 	  all text selected with the mouse is automatically
 	  copied to the Windows clipboard. (U)
  	> Paul Fox:
 	+ updated contact information in README, vile.1 and vile.hlp
 	> Tom Dickey:
 	+ allow a version number in rbmode (ruby) preamble.
 	+ add check in m4-filt.c for unbalanced quote, show the affected area
 	  as an error.
 	+ add ".ddl" suffix to sqlmode.
 	+ add ".dsr" suffix to vbmode.
 	+ fix makefile.blc, broken in 9.5f cleanup.
 	+ fixes for 64-bit warnings of Visual Studio .NET 2003:
 	  + modify Member_Offset() macro to cast the difference between
 	    addresses to a long rather than casting a pointer to a long.
 	    Use this flavor for Visual C++.
 	  + size_t is not necessarily the same size as unsigned - modify code
 	    to use size_t where it is consistent, otherwise cast as needed.
 	+ updated for python keywords
 	+ modify some lex filters, e.g., sql, to exclude \r in the places that
 	  exclude \n, since \r should not be colored.
 	+ fix for tb_enquote(); a value pointed to memory that had been
 	  reallocated.
 	+ make OBJEXT configure feature work for optional objects such as api.o
 	+ updated configure macros CF_CURSES_CPPFLAGS, CF_CURSES_LIBS,
 	  CF_NCURSES_CPPFLAGS, CF_PATH_SYNTAX, CF_WITH_IMAKE_CFLAGS,
 	  CF_XOPEN_SOURCE.
 	+ update config.guess, config.sub
 
  20060402 (g)
 	> Tom Dickey:
 	+ minor fixes to make most of the lex filters build with "old" lex,
 	  e.g.,
 		http://heirloom.sourceforge.net/devtools.html
 	  Note: the lex-filt.l file is too complex for some older lex's.
 	+ add lua mode
 	+ save/restore curgoal variable in b2vprintf() to avoid side effects
 	  when invoking "backward-row" or "forward-row" commands (report
 	  by Chris Green).
 	+ add delphi mode
 	+ add "*.cs" files to grep macros on win32 platform
 	+ improve csmode by making the section macros look for function
 	  headers.
 
  20060219 (f)
 	> Clark Morgan:
 	+ update vile.hlp for %n and %N title format changes.
 	> Tom Dickey:
 	+ fix sh-filt.l for parameter substitutions containing an escaped
 	  quote, e.g.,
 		VERSION=${VERSION#*VERSION \"}
 		VERSION=${VERSION%\"*}
 	+ add csmode (for C# ".cs" files) and cs.key, using vile-c-filter for
 	  parsing.
 	+ modify ntwinio.c to invoke build_recent_file_and_folder_menus() in
 	  the WM_INITMENUPOPUP event rather than WM_SYSCOMMAND.  This makes
 	  winvile initialize the recent-folders and recent-files if one uses a
 	  right-click on the title of the window.
 	+ change winvile's registry subkey for recent-folders and recent-files
 	  to match environment variable settings from 9.4r, e.g., change
 		"Software\winvile\MRUFiles"
 	  to
 		"Software\VI Like Emacs\MRUFiles"
 	+ add new symbols $return and $_ which can be used to implement simple
 	  functions (request by William James).
 	+ fix filters/makefile.2nd to allow build for gcov
 	+ improve majormodes for complex fences by initializing the (non-string)
 	  buffer mode values for submode groups according to the values in
 	  the submode.  This makes ignorecase work as expected in the complex
 	  fence matching for vbmode.
 	+ add complex fences to vbmode.
 	+ minor fix to bat-filt.l to avoid highlighting ".bat" as a string in
 		call foo.bat
 	+ change htmlfilt.l to highlight character- and URI-references as
 	  numbers to make them distinct from strings with ordinary text.
 	+ add makefile rules for installing/uninstalling files from doc
 	  directory:
 		install-doc
 		uninstall-doc
 	  as well as installing/uninstalling macros
 		install-macros
 		uninstall-macros
 		uninstall-perl
 	+ correct logic for goto-char, broken in 9.4za (report by William
 	  James).
 	+ fix change to cpp.key in 9.5e, which put the C keywords in the wrong
 	  table.
 	+ add spell.rc to makefile.wnt install rule.
 	+ add test_io.exe rule to vmsbuild.com
 	+ add TERM.clean(), TERM.unclean(), TERM.openup() to help move diverse
 	  code out of termio.c
 	+ modify var_TITLEFORMAT() only call set_editor_title() when setting
 	  $title-format, and modify get_statevar_val() to handle some limited
 	  recursion just in case there are other cases where it could be called
 	  from the statevar.c module while retrieving a value.  This fixes a
 	  bug introduced in 9.5e (report by Clark Morgan).
 	+ update title when doing a "cd", in case it uses %r substitution.
 	+ change %n in modeline substitutions to use file name (pathleaf)
 	  rather than relative path (shorten_path).  Use %r for the latter.
 	  (request by Clark Morgan).
 	+ move VMS-specific code from termio.c to vmsvt.c
 	+ remove unused start_debug_log() and mallocdbg() from main.c
 	+ correct typo in ifdef for Visual Studio C++ 6.0 ifdef in w32ole.cpp
 	  from 9.5e changes.
 	+ move 9.5c check for stdout not a tty on startup to allow "vile -V"
 	  to pipe to other programs.
 	+ split-out nullterm.c
 	+ add test_io stub, to help isolate dependencies of the I/O drivers.
 
  20060109 (e)
 	> Clark Morgan:
 	+ improved winvile's "flash".
 	+ several changes to w32reg.c:
 	  + if at all possible, don't register ole-enabled winvile using the
 	    path ".\winvile.exe" (obscure cygwin corner case).
 	  + remove use of toUpper(), which is not legit for winvile in this
 	    context because the underlying mapping array is apparently _not_
 	    initialized.  With this fix, "winvile -Ou" now displays the
 	    editor's name in MessageBox text (rather than "").
 	  + fixed lots of misuses of registry APIs (not properly testing return
 	    code).  With fixes in place, winvile -Ou/-Or now properly reports
 	    an error when registration/unregistration is attempted by an
 	    account with insufficient privileges.
 	+ add section definitions to vbmode.
 	+ fix:  wvwrap caused winvile to show an 8.3 folder name in Recent
 	  Folders list.
 	+ fix:  when CD'ing to a directory stored in winvile's "recent folders"
 	  list, the cursor stayed in the mini-buffer following a call to pwd().
 	> Tom Dickey:
 	+ adjust makefile dependencies to allow "make -j4" when building the
 	  loadable filter configuration (report by Ciaran McCreesh).
 	+ add "+", ",", "&", "@" and ";" to URL patterns in filters.
 	+ modify nr-filt.l to allow for optional blanks between the leading
 	  "." and the command.  This is common in nroff library macros, not
 	  in manpages, etc.
 	+ improve lex-filt.l, allowing for some flex extensions:
 	  + allow code in action rules to not have curly braces
 	  + allow curly-braces to surround chunks of flex actions
 	  + "*" as a state name.
 	+ add named marks for decimal digits (request by George Eccles).
 	+ fix stray ^@'s on the winvile popup menu resulting from changes to
 	  kcod2prc() for xterm-fkeys mode (report by Clark Morgan).
 	+ add a call to set_editor_title() at the end of swbuffer_lfl() to
 	  make title updates work properly with termcap configuration.
 	+ add %n and %N substitutions for $title-format (prompted by Clark
 	  Morgan comments).
 	+ modify FreeBuffer() to clear window's buffer-pointers that point to
 	  the freed buffer, e.g., to prevent reference to free memory in title
 	  updates (report by Clark Morgan).
 	+ check file descriptors in stdin_data_available() to avoid doing a
 	  fdopen() on an invalid descriptor.
 	+ add "#import" in cpp.key
 	+ modify preamble for xml- and html-modes to ensure that the first
 	  tag determines the type.
 	+ fixes to makefile.wnt and mkprlenv.wnt to work with Visual C++ 7.
 	+ correct padding of subtitle line for "Temporary variables" in
 	  [Variables] buffer, which was applied to all temporary variable
 	  lines.
 
  20051129 (d)
 	> Tom Dickey:
 	+ fix vl_ctype.h to avoid redefinition of UCHAR (reports by Clark
 	  Morgan, Mark Robinson).
 	+ fix lex-filt.l to build with lex (report by Dave Rolfe).
 	+ fix include-path in makefile.wnt, makefile.djg makefile.icc to work
 	  with split-out headers for regexp.c
 	+ remove code for DISP_IBMPC
 	+ remove makefile.emx and config.emx (obsolete).
 	+ remove makefile.wat and makefile.tbc, since they used ibmpc.c
 
  20051123 (c)
 	> Clark Morgan:
 	+ remove an obsolete comment in macros.doc regarding underscore in
 	  macro names.
  	> Paul Fox:
 	+ correct logic for check_percent_crlf(), ensuring that empty buffers
 	  are not counted as having CRLF endings.
 	> Tom Dickey:
 	+ fix to_tabstop() function used for :describe-bindings to ensure that
 	  a binding that happens to be 8 columns will still have a tab after
 	  it.
 	+ add a fflush() to ensure that the control string to reset xterm mouse
 	  mode is written during ^Z handling (report by Fabien Coutant).
 	+ add a call to term.kopen() in rtfrmshell(), making ^Z/resume work
 	  properly with the curses driver (report by Fabien Coutant).
 	+ make mouse work for curses driver just like the termcap/terminfo
 	  driver.
 	+ split xterm-specific code out of tcap.c as xterm.c, to share with
 	  curses.c
 	+ indent'd borland.c
 	+ remove ibmpc.c (obsolete)
 	+ check if stdout is not a tty on startup, print error message and
 	  exit (request by Paul Fox).
 	+ add mode xterm-fkeys, to allow termcap driver to generate
 	  shift/control/alt modifiers for function keys.
 	+ modify regexp.c so tab is not matched by \p or [[:print:]] for
 	  consistency with POSIX regular expressions.
 	+ modified regexp.c, add headers vl_regex.h, vl_alloc.h and vl_ctype.h
 	  to allow it to be easily built outside vile (request by Adrian Kole).
 	+ add KEY_BackTab to the output of show-key-names
 	+ fix kcod2prc() so that a shifted-tab is converted to "Shift+^I"
 	  rather than emitting a literal tab in the result.
 	+ update vilemenu.rc fonts to work on Debian/testing.
 	+ improve scrollbar/cursor tracking in winvile by calling
 	  gui_update_scrollbar() when WFMOVE flag is set (report by Deraj
 	  Puma).
 	+ add a simple csvmode for ".csv" files.
 	+ add ".ebuild" suffix for shmode.
 	+ improve mode-pathname for xresmode to handle things like KOI8Term.
 
  20051002 (b)
 	> Tom Dickey:
 	+ update config.guess, config.sub
 	+ improve os2vio.c, adding a check to distinguish between fullscreen
 	  and VIO to allow using bright background colors in the latter (report
 	  by George Eccles).
 	+ add KEY_xxx definitions to OS/2 and Win32 drivers, defining up to
 	  KEY_F35 for the former and KEY_F24 for the latter (report by George
 	  Eccles).
 	+ several improvements and fixes to lex-filt.l
 	  + expressions for regular expression parsing are more complete, which
 	    allows separating patterns from state lists.  That allows some
 	    error-checking in the rules section to flag spurious whitespace
 	    after a regular expression.  The more-complete regular expressions
 	    make the parser much larger (about 5 times the original size).
 	    A rewrite in C might be shorter.
 	  + ignore case of "%s" vs "%S" or "%state", etc.
 	  + parse the pattern names, applying highlighting to the names where
 	    they are embedded in regular expressions.
 	  + parse the "%s" (state) lists, applying highlighting to the states.
 	  + handle flex's <<EOF>> token.
 	  + handle character classes in the RANGE pattern.
 	+ remove an update() call from the logic in input.c which decodes
 	  hex/octal input after a ^V.  That caused the screen to move the view
 	  according to the address in the command, e.g.,
 		:%s/^Vx12
 	  would scroll to the bottom on entry of the "x" (report by Daniel L
 	  Ashbrook).
 	+ correct behavior of set-dos command, which did not recompute the
 	  buffer-size.
 	+ make end-of-token test for store-proc consistent with bind-key,
 	  i.e., alphanumerics and hyphen.  Amend that test to allow underscore
 	  (report by George Eccles).

 	> Tom Dickey:
 	+ review/improve vl-filt.l based on Verilog LRM draft
 	+ add configure check for lex's which support character classes, and
 	  add filters/noclass.sh to work around those which do not.
 	+ improvements to configure script from ncurses:
 	  + improve check for Intel compiler warnings
 	  + improve check for gcc version
 	  + define _QNX_SOURCE for QNX
 	+ revert part of 9.4n, which caused readin() to return false if there
 	  was no filename associated with the buffer.  Doing this broke some
 	  macros such as which-keywords (using buffer constructed by the
 	  macro).  Previously it returned true, indicating success.
 	+ improve parsing of range expressions in lex-filt.l, fixes a case
 	  exposed by css-filt.l
 	+ correct a case where slowread() in dosmode would compute a correct
 	  buffer size.
 	+ modify bat-filt.l to highlight "echo." consistently with M$ usage.
 	+ modify bat-filt.l to highlight "%*".
 	+ add syntax filters for bnf, css, midl, php and wbt (WinBatch).
 	+ modify syntax filters to use flex's character classes
