Re: Minibuffer default values list

    mailcap.el is located in the gnus directory, but it doesn't depend on Gnus.
    It doesn't load Gnus-specific files.

We should move it.  Where -- `lisp/mail'?  I am not sure, because
Dired's ! command has nothing to do with mail.

I suspect that there is a part of mailcap.el that is not specific to
mail, and that that is the part Dired uses.  Is that the case?
