The code seems to work (the resulting customisation option works),
but I was wondering a) if there are any hidden problems I'm not
aware of; and b) if there is a more canonical way of doing this.
If you have the GNU Emacs source, you can grep for "choice.*mapcar"
and see how others do it. I see 9 hits. I choose one that is from a
fundamental library -- minibuffer.el var ‘completion--styles-type’ --
and find it in the lisp/ChangeLog.16 entry dated 2011-10-03 authored
by Stefan Monnier. I feel comfortable using this technique now.
If you do not have the GNU Emacs source, then you can question your
sanity / situation / style / subjugation, until you do... :-D
