perhaps.

But what I had in mind is to add a bit to LINE's to note points at which 
the syntax filter gets back to the default state.  Those lines could be 
used (except for special cases like the keyword filter) to restart 
filtering at a given point close to the current window, and terminate when 
the before/after markers coincide.

Offhand, the biggest file that I find syntax highlighting useful on is
ncurses' terminfo file, and vile's a little slow on that one.
