Re: info inconsistency about "Shell Commands in Dired"

[Richard Stallman]

    IMHO, we should remove the feature all-together -- or just keep it
    as is and give a better example in the manual, e.g

            mv ? newname.c

    as well as warnings for things that does not work, e.g.

            mv ? ?-old

Sorry, I do not understand this text.  Precisely what is the feature
you propose to remove?  How would ? behave in dired-do-shell-command
after your proposed change?
