Syntax highlighting can and often does depend on buffer contents after 
the region.

It's one thing to mis-highlight a part of the buffer because the 
contents are incomplete (the user hasn't typed the full expression).

It's another thing to mis-highlight it because the chunk requested by 
jit-lock ended on a particular ambiguous position.
