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