shrink_windows is called with a min_size argument of 1 if shrinking
heights.  That's all I can observe.  The bug goes away when I call it
with min_size 2.

That's why shrink_windows would have to check for every window whether
it has a modeline and not resize it if it has one and its actual height
is 2.
