I see.  I don't really have any good suggestions here -- there is the
_complete_fallback idea but all it does is provide alternate guesses
for the possible argument positions, which doesn't help in this case.

It might be do-able to revert to executing run-help when there are no
completions found, but that would be wrong in a lot of cases (e.g.,
on file name not matched, displaying a manual page isn't useful).

} I might have tried grep --binary and nothing would be returned because

No complaints, no.  It appears from cursory examination that the person
who initally wrote _grep only had access to GNU grep, and _grep has had
only a few minor updates since 2002.

} Menu selection (the zsh/complist module) has an incremental search, so
} what you describe above can already be done.

I think Sebastian wants to search through the descriptions, whereas the
complist search only examines the completions themselves.

None of this helps with the situation Sebastian described above wherein
the completion results/descriptions do not include the desired content.
