Ah, I see.  So the idea is to allow (say) image/png to override image/*
without the sorting having to be explicit.  This allows the user to
provide defaults for the stuff not specified in the built-in alist.

It makes sense, I guess, but if the user really wants all image/* types
to go somewhere specific, then there's no way to do that the current way
it works, which sucks.

Right...  so perhaps the best solution here would just be to add the
"priority" stuff to mailcap.el?  Then you can say

image/*; xloadimage %s; priority=5

to use xloadimage on all the images?

No Gnus/Emacs 24 is in a feature freeze at the moment, though, and this
would count as a new feature, I think, so implementing this would have
to wait a bit.
