bug#38181: Actual height of mode-line not taken into account

'window-text-pixel-size' does it (triggered by the sixth argument
MODE-AND-HEADER-LINE non-nil).

Possible, I think.  If we pass it on to 'window-text-pixel-size', it
wouldn't even have to be Lisp-callable.  Still, it will penalize every
‘fit-window-to-buffer’ call (without a redisplay, though).
