I wasn't seeing anything for an inlined message/rfc822 part (as with a
forwarded email message) and discovered that for some reason, the
message structure wasn't as expected. The following patch appears to
help me.

I'm still stuck trying to use the 'v' key to display attachments from
forwarded messages; it looks like mm-dissect-buffer isn't digging into
the attached message and pulling the embedded attachments out or something.

However, I can at least view the message and save the attachments now.
