Anything that depends on %{...%} to tell the prompt code (and by
extension the completion code) where there are cursor movements that
shouldn't be counted as part of the shape of the prompt, is going to
become broken if PROMPT_PERCENT is turned off.  There are a couple of
things in the Functions/ tree (some of them written by me, I see) that
assume PROMPT_PERCENT is active without asserting it, but I don't see
anything like that in the Completion/ tree.
