Re: Bug: C-h c gives the wrong answer for a menu item, and fails to display it.

[Richard Stallman]

    This puts the message "C runs the command tmm-shortcut" in the *Messages*
    buffer.  This is wrong:

    (i) The correct answer is, of course, "C runs the command cua-mode".
    Saying "tmm-shortcut" is just as true and just as helpful as saying
    "C-M-a runs the command eval".

I don't think this answer is false, but I agree the answer is unhelpful.
To make it better would require special-case code.
Would you like to implement it?
