Ouch. Pasting the code into a wterm messed up indentation pretty
badly. )c:

The function actually used in AUCTeX does a bit more. For example it
checks if a face for verbatim content is present and does not set a
match in such a case.

Hm, I would not like leaving people who disabled jit-lock out in the
cold. So the hook is probably a better alternative. But thanks for
that hint anyway.

I am tempted to disagree but maybe this is a case of getting used to it.

Hm, how would it be possible to detect closing tags in this case?
Maybe with an initial search for these tags across the region to be
fontified. Or on a case by case basis for every closing tag which is
encountered during fontication of the region? This would be rather
inefficient compared to using a hook to be called before
`font-lock-after-change-function'. But maybe you are thinking about
something completely different.
