Hmm... good point, doing it in completion-choices is not reliable, tho
using as completion table something like:
(lambda (string pred action)
(let ((res (complete-with-action action completion-choices string pred)))
(if (and (eq action nil)
(assq (if (eq res t) string res) <expansion-alist>))
(cdr (assq (if (eq res t) string res) <expansion-alist>))
res)))
should work OK for prefix completion, but that means using the expansion
"by hand" rather than via expand-abbrev, which may not be an option.
