It would be relatively easy to make it remember how long the list
below the prompt is (it should already know about the presence of a
list -- at least in most cases).

So, are you suggesting a zle-option to make it put the prompt `below
the list if there is one'?


If you are only concerned about completion: there is the last-prompt
style. But unfortunately, this doesn't work with _complete_help
because that doesn't set up it's own $curcontext, and, I think, it
shouldn't because we call it to get information about normal
completion in the same context. Hm. We could make _complete_help test
the last-prompt style directly with a context like
`:completion:complete-help::::' and if it is true, set
`compstate[last_prompt]=yes'.
