Did you try to make a rule like this:
    tag </(frame|script)/i>
?

That won't work...the code that grabs out the regex is pretty dumb.  It just
looks for /(stuff)/ and doesn't try to grab any modifiers.  The modifiers
applied to FilterProxy regexes by default are "isx".  (i because html is ca=
se
insensitive, s because the whole file is matched against, and x for obvious
reasions -- see the ADS rule)  Allowing modifiers wouldn't be terribly
useful... (which modifier would be useful?)

I'll make a note about modifiers in the Rewrite html file.

You're welcome! :)
