Bug#441785: Umlauts break syntax highlighting

[martin f krafft]

I boiled down the problem to the vimoutliner syntax definition:

  :syntax region OL2 start=+^\t[^:\t]+ end=+^\t[^:\t]+me=e-2
  contains=outlTags,BT2,BT3,PT2,PT3,TA2,TA3,UT2,UT3,UB2,UB3,spellErr,SpellErrors,BadWord,OL3
  keepend

The problem here is the offset for end: me=e-2. This basically means
that at level 2 (one leading tab), the match region ends on the
first character that's also at level 2 (unless it encounters a match
region not in the set specified by contains), minus 2 (the character
and the leading tab).

Vim seems to use bytes instead of characters here though: the syntax
highlighting only breaks when a UTF8 character is the first of the
heading, in which case the me=e-2 offset somehow gets lost and the
OL2 region is extended to the *next* level 2 heading.

Using me=e-3 or me=e-1 both work, which really does not make sense
to me.

Sven, this remains a bug in vim, I think, and I don't see a way to
work around it in vimoutliner. If you want to help fix it, bring up
the issue on the vim mailing list (and CC this bug report).
