ick, how is this scoped? can you not have them removed instead?

[brettw, 2014/05/12 18:06:41]

This is the only solution now. I could put the filter back when I'm done, but
that's a lot of processing to re-parse all the regexp's, and we don't need that
here. Suggestions welcome.

Maybe there should be a way that something like this could just temporarily set
it to [] and then reset it back to what it was.

[brettw, 2014/05/12 21:00:08]

Okay, I put it back, although I was avoiding this because it's not useful, maybe
it will bite somebody someday.
