This was from emacs -Q. On my machine (running Ubuntu), with a
maximized frame, increasing the font-size doesn't make the frame
larger. Maybe it's a difference in the OS (I think on Windows if you
increase font-size the frame does get enlarged).
The point is that the combination of font-size and frame-size has to
be such that two windows do not fit side-by-side. In this situation,
Emacs usually creates temp windows below the current window (instead
of to the right). Here's a new recipe to verify what I'm explaining
now.
0. Start emacs -Q
1. Resize the frame so that it is less than 30 columns wide, and at
least 30 lines tall.
2. Type `C-h f point RET'.
3. The temp window is created below.
Now here is an updated recipe for the original behavior I was
describing (the fact that windows are vertically expanded to fit the
help buffer).
0. Start emacs -Q
1. Resize the frame so that it is less than 30 columns wide, and at
least 30 lines tall.
2. Type `C-- C-5 C-x C-2', to create a tiny window below.
2. Type `C-h f point RET'.
3. The temp buffer is displayed in the window you had created, and the
windows size is increased to half the frame.
4. If you hit q on that help window, it will return to the original
height of 5 lines.

This sentence was part of the explanation leading up to the next one.
The next sentence is the one that describes the behavior I get. Sorry
if I wasn't clear.

Some edebugging shows me it is done by
`display-buffer-use-some-window', and indeed I see a `window-resize'
in there.
