I added `auth-source-read-char-choice' to do the prompting.  It will use
`read-char-choice' opportunistically and construct the a/b/c prompt
supplement automatically.  If you want me to modify `y-or-n-p' to use
`read-char-choice' let me know and I'll submit a patch.

Try (dropdown-list '("choose one: y" "............n" "............N"))
since that's how it will look with the new
`auth-source-char-read-choice' function.

I disabled `dropdown-list' in that function because it didn't work when
called from the :save-function lambda, although it worked interactively.
I think it needs to be outside the echo area but couldn't figure out how
to fix it.  Can I say "switch to any non-echo area window"?
