p0.84: Difference in use of "message/rfc822" content type

[Karl Kleinpaste]

When I use gnus-summary-mail-forward (`S o m'), Gnus manufactures a
message buffer containing a Content-Type: message/rfc822.
                                                     ^ note

When I just now replied to some other mail and also wanted to include
yet another item of mail, I used `C-c C-a', and when offered the
content-type prompt, Gnus auto-completed on message/rfc-822.
                                                       ^ note

I believe that the latter version is incorrect, so that the 5
occurrences of that string in mailcap.el need to be changed:

--- mailcap.el.~1~	Tue May  4 13:24:24 1999
+++ mailcap.el	Tue May  4 13:23:53 1999

       (viewer  . "xwud -in %s")

Alternatively, if "with dash" is correct, then the occurrences of
"rfc822" in message.el, mm-{en,de}code.el, and nndoc.el need to be
changed.

If both are acceptable, then at least nndoc.el needs to be changed to
make the detecting regexp general to both forms.
