Re: Minibuffer default values list

[Richard Stallman]

Thanks for implementing this feature.

    Now I propose to improve dired-x to read a list of commands from the mailcap
    mechanism, and later to move this code to dired.el.  An alternative would be
    to start implementing this in dired.el (provide a list of mailcap commands
    available via M-n), but then after loading dired-x users will get less
    useful list of commands in ! (since this is not implemented in dired-x).

You could put this code in both.  dired-x is not used by most users,
so having it only in dired-x is not very useful.
