[PATCH] emacs: Fix handling of message/rfc822 parts.

[Jameson Graef Rollins]

After the recent part-handling overhaul, emacs handling of
message/rfc822 parts broke, not outputting the message contents.  This
"fixes" then handling as is, but there are still problems with how
notmuch is outputting message parts that needs to be addressed (for
instance, message headers are not being output at the moment).

This also indicates that we need a test for output of message parts in
emacs.
