Patches are welcome to pop up the menus so that they never overlap the
echo-area when tooltip-mode is nil.  (This must be done up front, when
calculating where to pop up the menu.)

I do note that the most important use case where this comes into play,
which is menus on text-mode frames, already behaves that way.  So the
problem is rather small and confined to a somewhat marginal use case.

Thanks.
