A few years ago I wrote a filterfs exclude files matching a
regular expression.  We use it on our web site when publishing
part of the dump file system since, as people have noted in
the past, there can be times when you need to effectively
delete things from Venti.

It's not polished so we never put it on sources, but I'm
willing to do so if there is sufficient interest.

Bind(1) does not have an "exclude" function that I can know of,
which means that exclusions can only be effected by enumerating
the inclusions.  This can get extremely tedious.
