'?' is an automatic option added by read-multiple-choice.  It pops-up an
autogenerated buffer repeating the prompt and showing longer
descriptions for each option.

I would have liked '?' to show what I ended up putting in the "details"
buffer; ideally read-multiple-choice would have an optional HELP-MESSAGE
argument that could be squeezed between the prompt and the key
description when showing the help buffer.

Since that's not how things work, I went for the additional option
('d').

I didn't know about read-answer, that was an interesting discovery.

read-multiple-choice only accepts single-key answers, you cannot answer
with long options if I'm not mistaken.  You cannot choose what the
prompt looks like either; you simply provide a list of (KEY NAME
[DESCRIPTION]) tuples; NAMEs will be shown in the prompt, DESCRIPTIONs
will be shown in the auto-generated help buffer.

(Let me know if that does not answer your question; I might have
misunderstood.)
