Resetting LINES afterwards fixes ^L and the printing of the selected
word twice, but it doesn't stop the previous line from being eaten:

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

I'm not sure why it only works by setting a local LINES at the end,
but it seems to be the only combination that works.
