Thanks for the tip. This works fine in emacs 23, but not on 21.4,
where it gives the error "invalid regular expression".

Do you have any idea how to get this working in 21.4? font-lock itself
seems to work OK, it really does seem to be a problem with the regex.

Please cc me on replies, as I am not subscribed.
