Title: deal with cross-posting

Trim `Re: [foo]`, `Re: Re: [foo] [bar]` and similar from the `Subject:` header, since cross-posting to multiple lists can result in different `Subject:` header prefixes.

It seems to work fine for me but I did this in a hurry so please sanity check before merging! Thanks!
