It depends how do you use compctl -X.  I used in in exatly the opposite
way: for example for dd, I complete filenames after if= but when I hit
TAB after bs= zsh will print <number> (see Misc/compctl-examples), and
that's always worked at least since zsh-2.5.  Older versions had an
nmatches != 1 test here: if there is a unique completion, do it and do
not disturb the user.  If there are no or more than one completions,
explain.  It was an oversight from me (that I made last August, almost a
year ago) to change it.  The patch below restores the original behaviour.
