new slang2 snapshot

["John E. Davis" <davis@xxxxxxxxxxxxx>]

Today I released another development snapshot of slang2.  This is a
bug-fix release that should fix a few of the problems that have been
seen by some jed users.  You can get it from:

    ftp://space.mit.edu/pub/davis/slang/2.0-devel/slang-pre2-r2.tar.gz

Changes since 2.0.0 pre-release 1
1. slsh/lib/require.sl: Protect the Features variable against multiple
   loading.
2. src/*.c: VMS-specific patches from Jacob (=Jouk) Jansen.
3. src/slsearch.c: non-UTF-8 case-insensitive searches were not working.
4. src/SLwchar*.c: SLwchar_xxxx functions will use the current locale
   if UTF-8 has not been enabled for the interpreter.
5. src/sldisply.c: The display of double-wide unicode
   characters was not working properly under some conditions.
6. src/slsmg.c: If a double wide character is being displayed, then if
   a character is written to either of the cells occupied by the
   double wide character, then the opposing cell will be overwritten
   with a space.
7. src/sltoken.c: Characters specified as 'x' where 0 !=(x&0x80) were
   not being properly parsed.
8. src/aclocal.m4: --without-foo was not working.
9. src/slstrops.sl: Fixed an access error in the "string_match"
   function.

Thanks,
--John
