| ah, I see. thank's a lot! -- so I've just download 9.8o and it
| installed
| just fine (always happy when an install just runs through...). I can
| confirm that the problem is mostly solved in this version. but in
| fact the
| highlighting still behaves a bit strange: the `"$fdiff"' in my
| example
| (the source for the redirection) is now displayed in inverse video of a
| keyword if I enter the editor and do a search for `<<<'. if I then enter
| other search patterns moving me away from the `<<<' line the inverse video
| does change randomly it seems over the range of `fdiff' but does not go
| away completely. if I initially search instead for, e.g., the `while',
| i.e. jump to another line with the search the inverse video effect does
| not happen and everything looks fine. no complaint, just an observation ;-)

thanks (I'll take a look - fixing syntax filters is often not that hard...)

| thanks again for the hint. I think I'll stick with 9.8o if nothing speaks
| against this.

sounds good (I've been a little slow on 9.8q - too many pots on the stove...)
