Thanks for the advice.
It's a very small hack to view
grep xyz * | vim -
so i'm not that worried about clearing of syntax.

map <S-F10> :syn match PreProc "^[^:]\+:"<CR>
vimSynRegPat #1: ^^^^^^^^^^
vimSynRegPat #2: ^^^^
vimSynRegPat #2 never ends looking for the enclosing "<"
that should match end="\z1"
( for start="\z([[:punct:]]\)" that matched "<")

OK. I see now.
I think i should give it a try to correct vim.vim now that you
explained me what's going on ;)
Any ideas how this should be done in a straight way ?
I suppose vimSynRegPat should be excluded from
syn cluster vimSynMtchGroup
so it won't match several times but what than .... ?
