Imprecise again: The above covers only the automatic resizing triggered
by redisplay (which is what we are interested in).  Manual resizing the
minibuffer window is done in 'window--resize-mini-window' (also in
window.el) so if such manual resizing may happen in between you have to
instrument that as well.
