kill-buffer--possibly-save uses a different form of calling
read-multiple-choice, which presents a slightly different UI, see the
doc string of read-multiple-choice where it describes the LONG-FORM
argument.  One side effect of this way of invoking
read-multiple-choice is that the users must type long responses,
i.e. they cannot just press a single key; this would be annoying if
nsm used it.  Another side effect is that GUI dialogs cannot be used,
which I think would be a UX problem with nsm.  It's also slightly less
clear in the prompt text it shows.

Once again, the nsm prompt is AFAIU intentionally programmed to work
like it does, for more than one reason.  I don't think it's TRT to
change the way we call read-multiple-choice in this case, since the
nsm prompt could appear several time during fetching a URL, and being
able to press a single key is a huge bonus.

The best solution to the original problem suggested so far is what
Andreas suggested: a special command to show the information.  Patches
to that effect, as well as other ideas that don't affect how
read-multiple-choice works, are welcome.
