Here's a patch to get rid of extra Re:'s around the beginning of the subject line. I don't know whether this replaces too aggressively or not (I'm testing it on a largish mailing list). Probably not. Another question is that should we have

 Re: PREFIX .*

or PREFIX Re: .*

in replies. I'd maybe favor the latter (this is also what the patch implements).
