Yeah.  But shouldn't we have a general multiple-choice library function
for these (sort of) extended y-or-n-p functions?

While writing the NSM function, I was looking around for one, but the
only thing I found was `gnus-multiple-choice'.  :-)  So I had
implemented this before.  A call using that function here would be

(gnus-multiple-choice "Continue connecting?" '((?a "always")
                                               (?s "session only")
                                               (?n "no")))

Or something.  If the user types something else, you get a help buffer
and stuff.

Shall I make that into a general function (it needs some tweaking in the
prompting department)?
