Hi.

I like occur a lot, but I find it inflexible -- the matched lines can only
be specified by a regexp.  I'd like to be aple to pass a function to occur
instead of a regexp.

The function should be called with point at the beginning of a line to
match/not match, so that

  (occur regexp)

is equivalent to

  (occur #'(lambda () (looking-at regexp)))

Of course, the function should be able to examine the context around the
line being matched.
