One tweak might be nice first: if a completion widget, for example
complete-word, is rebound, then `zle -C ... complete-word ...' doesn't
work; you need .complete-word.  There's no reason in this case why we
shouldn't use the immortal version with the `.' in front all the time,
since the intention is unambiguous.
