I spoke too soon.

It looks using a custom function bound to the tab key causes some
problems, even without setting LINES.

Now when I get to the end and cycle back to the top, the prompt goes
up and overwrites the previous line.

This is what I'm using:

zle -N _vi-tab

_vi-tab() {
  LINES=15 zle complete-word
  }

bindkey '\t' _vi-tab

Any ideas?
