Yes, but do you understand why it's a problem anyway?  Lazy hilighting
uses the same regexp search functions and the same regexp as the code
that find the first hit.  We are talking about 2 cases where there's
no other matches for that regexp.  So how come finding out that there
are no more matches is almost instantaneous, but looking for them as
part of lazy-highlighting is so slow?
