Sounds like a job for mhfixmsg, I'll look into it for 1.7.  It would
probably go into the small category of things that it fixes
unconditionally.

The question remains of whether mhstore should decode 2047-encoded
filenames natively.  It'd be friendly and it's very unlikely that what
looks ike an encoded string isn't.  On the other hand, running mhfixmsg
shouldn't be prohibitive.
