If a function doesn't actually change font-lock-{beg/end}, it should
return nil.
And yes, the risk of inf-loop is a problem, but I don't know how to
solve it, because counters aren't really a solution either.
Maybe I could simply impose an arbitrary limit so we can't go through
the loop more than 10 times (or N times, N being the length of
font-lock-default-fontify-region).
