Message forwarded.

After displaying the headers, I get this from 'show':

mhshow: don't know how to decode content
        (content text/plain in message 10)

and it exits. It's not crashing, but I wouldn't mind if after getting
this error message, it tried dumping the offending MIME part into less
as a fallback. All I really want is a shot at looking at the contents
without having to do anything special.

What you're describing here is far beyond what I was intending; I only
want a seamless way to apply my eyeballs to these broken messages.
