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

Yes.  But, as I mentioned earlier, the problem shows up with the
scroll bar immediately when Jonas' form is evaluated, see the attached
screenshot.  Code like 'fit-window-to-buffer' works on the text area
only, it doesn't care whether a scroll bar or mode line changed size
since last redisplay.
