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".
