It's debatable whether everyone will like this.  For example, my main
code-editing frame always has a window at its bottom where I display
stuff like *Help*, *Apropos*, and commit logs, and I like to keep that
window's height small at all times, once I resize it manually to the
height I like (I have the resize-temp-buffer-window-inhibit option set
to 'vertical').

So if we introduce the above feature, it should be controlled by a
user option.
