* You can now set a per-file tab style, that differs from the defaults established
  in the ED hook.
  This is important especially since we do not yet support per-project .teco_ini
  scripts where you could establish differing policies depending on the VCS repository.
  (The latter would be easy to implement, but we cannot currently easily extend the
  existing ED hooks.)
* It's unlikely that files contain an ASCII 27, but not impossible.
  Therefore we now use ASCII 0 (^@) as a terminator.
  This indeed be safe under UNIX.
  Even better would be a string building construct for escaping ASCII 27 ($), though,
  as that would work with arbitrary bytes.

* should also fix Win32 nightly builds
* Even though we weren't using main's argv, but were using glib
  API for retrieving the command line in UTF-8, newer MinGW runtimes
  would fail when converting the Unicode command line into the system codepage
  would be lossy.
* Most people seem to compile in a "manifest" to work around this issue.
  But this requires newer Windows versions and using some Microsoft tool which isn't
  even in $PATH.
  Instead, we now link with -municode and define wmain() instead, even though we still
  ignore argv. wmain() proabably get's the command line in UTF-16 and we'd have to
  convert it anyway.

* This was accidentally installing into $bindir/usr (usually /usr/local/bin/usr/...)
  You might want to check whether SciTECO accidentally installed something there.

The next release will include almost exclusively bug fixes.

* The line drawing algorithm currently works only with tbl, though.
* Also only straight lines are currently supported.
* This was meant for rendering presentations in SciTECO - it's not currently
  used or planned to be used in the manpages.
  Although we might well add pic graphics to the manpages in the future.

This could theoretically be used to apply Scintilla styles not natively and easily supported by grosciteco,
eg. different fonts and font sizes.
