bug#22684: 24.5; Gnus seems not to understand wildcard mime types in mailcap files.

[Ben Bacarisse]

With no ~/.mailcap file:

1. Start message mode

2. Eval (mailcap-parse-mailcaps)

3. Eval (mailcap-mime-info "video/quicktime")

4. Note what the view handler is (it's mplayer on mys system).  This
   most likely comes from comes from /etc/mailcap.

5. Create a ~/.mailcap file with a line

   video/*; totem %s

6. Either force a re-parse with (mailcap-parse-mailcaps nil t) or
   restart emacs -Q and do steps 1 and 2 again.

7. Eval (mailcap-mime-info "video/quicktime").  This will be unchanged
   but I think the local setting should take precedence.  Other programs
   (run-mailcap, mutt, mhshow) certainly now use totem rather than
   mplayer.

8. Change ~/.mailcap to have a non-wildcard type:

   video/quicktime; totem %s

9. Repeat 6 and 7 and you see the user's mailcap choice of handler as
   I'd expect.

mailcap.el chooses the most specific entry, no matter what the order of
the entries are.  So if you have a video/quicktime somewhere, you can't
override that by just saying "video/*" in mailcap.el.  I think that's a
pretty odd way of doing things, but it's been that way since, well,
forever, so it's not exactly a bug...

Thank you.  I should have thought of that.  It makes choosing your own
handler fiddly, but at least I know what's going on.  Thanks again,
