I have received email with C-T-E set to binary.  While I don't think it
was needed, I haven't checked closely.

This might not be much of a lift.  m_getfld might handle NULs in bodies,
and the MIME parser comes close to handling them as well.

mhshow has a test-binary that says that it reads a null byte, but it's
just a space.  That should be fixed, but I think that might reveal
(minor?) deficiencies elsewhere.
