[RFC PATCHv2 7/8] vim: mailcap: show all alternatives if none preferred

[Nick Howell]

Display all parts of a multipart/alternative message (or message-part)
if no alternative_preference matches any of the alternative mimetypes.

E.g. if a message is multipart/alternative with options text/plain and
text/html, and the alternative_preference is ['application/pdf'], no
preference option matches any of the parts. This patch would just
display both parts.

Better configuration is to have '*/*' as an option in your
alternative_preference, e.g. ['text/plain', 'text/*', '*/*'], so that
there is always a catch-all.
