m_getfld and the MIME parser do handle NULs.

post(8) doesn't.  I'd like to commit the attached patch.  It uses write(2)
instead of fprintf(3) and fputs(3).  All tests pass with it.  Any objection?

While SMTP servers still might not be able to handle NULs, I don't think
that nmh should block them.

That was incorrect.  printf(1) wrote out the NUL.  I'll add a comment to
the test to make that clearer.
