Please show the output of each one the following forms, evaluated in
both the "good" and "bad" configurations, when you start "emacs -Q"
and visit the same /dev directory:
(window-height)
(window-pixel-height)
You can evaluate each form using M-:, as in
M-: ((window-height) RET
Please compare the return value of window-height with the actual
number of lines available in that window, and tell if the two match.
