I couldn't think of a particularly better solution. A nasty hack would
involve looking at $compstate[nmatches] to see if anything else had
been completed but you can't rely on the options be completed after
whatever else. postfunctions aren't much use because they are run too
late after all the completers. In some respects prefix-needed is
actually redundant because the same can be achieved with the
ignored-patterns style.

So your -O is probably the best solution.
