Please do not have a look at that.  It does things it shouldn't do;
ignoring OT1H and messing up OTOH the 'quit-restore' parameter of the
(re-)used window.

Please try the now attached version of 'display-buffer-below-selected'
instead.  The idea is that when you call

(display-buffer-below-selected BUFFER '((window-min-height . 40)))

it makes sure that the window used has at least 40 lines or can be
resized to 40 lines at least.  To really make the window 40 lines tall
you have to use 'window-height' too, like

  BUFFER '((window-min-height . 40) (window-height . 40)))

Obviously, 'window-height' may have a different value than 40 and
'display-buffer' will then try to use that value if it is allowed to
do so.  This means that

  BUFFER '((window-min-height . 40) (window-height . 20)))

may fail if the window can be made 20 lines tall but not 40.  But if
the window can be made 40 lines tall 'display-buffer-below-selected'
will try to make it 20 lines tall.  OTOH

  BUFFER '((window-min-height . 40) (window-height . 60)))

will fail only if no 40 line tall window can be found or made.  If
subsequent resizing to 60 lines fails, the window will stick to the
preexisting height (which can be the result of a split).

Is that all sufficiently comprehensible and coherent?
