I tried to encapsulate the actual filter implementation
so it could be replaced by something nicer later.
I considered using regexps, but that seemed (a) insecure,
(b) more complicated, and (c) harder to use for my application.

I'm going to use my patch as-is for now, but would be
happy to consider improvements if anyone had concrete suggestions.
