the '?' in read-multiple-choice prompt

the '?' in read-multiple-choice prompt

[Shynur Xie]

The function `read-multiple-choice' always display a '?' in the
prompt.  E.g.,

    (read-multiple-choice "prompt" '((?a "alpha")))
    ;; prompt (alpha, ?):
                      ^
            How can I discard it?

Moreover, if evaluating

    (read-multiple-choice "prompt" '((?? "question")))
    ;; prompt (? question, ?):
               ^           ^
         How to distinguish them?

That behaviour is currently hard-coded, but it would be easy to patch:

Now

(read-multiple-choice "prompt" '((?a "alpha")) nil 'no)

does not add a question mark, and

(read-multiple-choice "prompt" '((?? "question")) nil 'no)

still returns "question".

Thanks a lot!

Will it be installed in one of Emacs branches?
(so that I don't need to modify the definition manually.)

I don't know, you can submit a bug report to bug-gnu-emacs@gnu.org with
the diff I sent you to have it discussed.
