We had a discussion in November regarding the multipart boundary values
that nmh uses, and how it broke one particular mailing list software.

I just received an email with this:

Content-Type: multipart/alternative;
        boundary="----4Oz1uemc|;yeFynqec7gEs^b|e.m;"

And that, it turns out, breaks exmh (it looks like the problem is the
semicolon).  But nmh is fine with it.

Crap.  I thought I went through the exmh code a while ago and fixed a bunch
of bugs having to do with properly quoting and escaping text controlled by
a remote user/adversary.
