I don't oppose mailcap-user-mime-data but I think user shouldn't be
forced to duplicate his mailcap configuration inside Emacs.
Does that suggestion really require duplication, or does it require to
have only those (hopefully few) entries that override the default?
User already has his system's mailcap settings and many programs
respect that. Why doesn't Emacs? (Ok, it does but with its own
preferences of doc-view-mode etc.)
Because doc-view-mode is specific to Emacs?
How about a variable like mailcap-prefer-system-mailcap with a non-nil
value would put the priority of doc-view-mode (and every viewer Emacs
offers) below system's mailcap configuration?
That'd still require a separate customization in Emacs, so I wonder
how it is better than what Tassilo proposed.
