Of course, I already noticed that this part is eligible for optimization
in one `or', but I decided to try writing a close equivalent of
C code in Lisp, so it would be easier to put both versions side-by-side
(in horizontally split windows ;-) and compare their logics.  And I wrote
about this fact in the docstring as:

  This function tries to match the implementation of vertical splitting
  in `display-buffer' as close as possible but with the logic of
  horizontal splitting.

Not a big deal, I think.
