Thanks.

The alternative would be to treat the nil return value from
try-completion here:

              (let* ((prefix (try-completion fixed comps)) <<<<<<<<<<<<<<<
                     (unique (or (and (eq prefix t) (setq prefix fixed))
                                 (and (stringp prefix)
                                      (eq t (try-completion prefix comps))))))
                (unless (or (eq elem 'prefix)
                            (equal prefix ""))
                  (push prefix res))

as if it were "".  Would that be better?

With the change I proposed, "C-h v -l TAB" deletes "-l" that the user
typed -- is that the expected result when there are no completions?
