It depends on what you want.  You can resove the example in your
original posting

> 1. Emacs -Q
> 2. (temp-buffer-resize-mode t)
> 3. M-x calc
> 4. h h

by doing

(setq temp-buffer-max-height
      (lambda (buffer)
        (max
         (window-total-size)
         (/ (- (frame-height) 2) 2))))

in your .emacs (personally I think that this should be the default
value).  If you refer to Jay's remark

> I've never used temp-buffer-resize-mode before, but if it's supposed to
> make a window a better size for displaying a temporary buffer, I'm

that is you want to get the *scratch* window back in its original size,
then typing "q" in the help window should do what you want.
