vile 9.8 is released.  The goal of this release is to fill in the remainder
of the UTF-8 support.

General changes:
  + many improvements to UTF-8, for regular expressions and input.
  + implement user-definable operators
  + vile.hlp and all ".doc" plain-text files are generated from html.
    http://invisible-island.net/vile/vile-toc.html
  + highlight matches in which-keywords, etc., and put a hyperlink on the
    highlighted text to view the corresponding file.
  + add a brief mode format "%M" for modeline-format
  + improve checks for insecure file permissions.
  + improve which-source and which-exec commands, showing which files
    fail the checks for insecure permissions.
  + new configure script options:
  + --with-symlink, which augments --program-suffix to make it
    simple(r) to install versioned binaries.
  + options for transforming program name upon install:
    -- program-prefix, --program-suffix, --program-transform-name

Locale Improvements: (too many too list)
New Commands:
  + new command-line option "-F" tells vile to only run the syntax
    filters for the given files, writing the attributed text to the
    standard output.  Used this option to highlight the code-examples in
    vile's html and documentation.
  + added several "list-XXX" aliases to match "show-XXX" commands, for
    consistency.
  + "append-number", "insert-number", "overwrite-number" commands work
    with characters entered as numbers.
  + "define-menu-entry" modifies xvile menu entries.
  + "set-extra-colors" allows setting extra colors for special buffers
    such as [Settings].
  + "show-filtercolors" macro shows the class names and their colors for
    the current majormode.
  + "show-extra-colors" shows classes and colors modified by
    "set-extra-colors".
  + "show-local-modes" is an easier-to-remember variation for the
      count+"show-modes" combination.
  + "show-undo-stack" shows the contents of the undo-stack.
  + "show-wide-printable" provides a way to see details for other "pages"
    than the ASCII/Latin-1 0-255 code.
  + "store-operator" stores a macro which is treated as an operator.

New Modes:
  + "spaces-after-sentence" is now a buffer mode, to allow it to be part
    of a majormode.
  + "check-access" makes the check for insecure file-permissions
    configurable by the user.
  + "percent-autocolor" can be used to override the autocolor mode for
    very large files.
  + "reuse-position" allows users to specify that vile should restore the
    current line/column position when (re)displaying a scratch buffer
    built with liststuff.

New Variables and Functions:
  + &bchanged, &fchanged and state variables $bchanged (same as
    $modified) and $fchanged make it simpler for scripts to check if
    buffer/file timestamps differ.
  + $cfgopts now shows drivers (ansi, borland, ntcons, ntwin, os2vio,
    vmsvt) and other useful settings (iconv, multibyte).
  + $cmd-encoding variable allows control of minibuffer's encoding
  + $cmd-motion variable is used in user-defined operators.
  + $font is always available, but readonly for non-GUI configurations.
  + $kill-size and $kill-limit variables to improve scripting with the
    $kill variable.
  + $latin1-expr variable specifies whether a derived narrow locale
    really has Latin1 (ISO-8859-1) encoding.
  + $modeline-limit limits the offset into each line that vile scans for
    modelines.
  + $term-cols, $term-lines and $term-resizes give the terminal
    dimensions, and tell if it is in a resizable window.
  + $title-encoding controls whether vile 8-bit or UTF-8 encoding is used
    when setting xterm title.
