I'm not sure the following indicates a bug (or bugs), but it at least
shows differences with respect to using the mouse to resize split
windows where I would, from the user's point of view, expect to have
symmetry.

1. emacs -q

2. M-: (setq mode-line-format nil)

3. Type `C-x 2'. Now the frame is split vertically into two windows,
but the only visual indication of the split is two cursors, and there
is AFAICT no way to resize the windows by dragging the mouse.  

4. Type `C-x 1' and then `C-x 3'.  Now the frame is split horizontally
into two windows, visually obvious due to the scroll bar, but here too
there is AFAICT no way to resize the windows by dragging the mouse
(there is no "handle" under the scroll bar).

5. Click in the righthand window, giving it focus, then click with
mouse-1 in the echo area.  Now the lefthand window (the *Messages*
buffer) has a mode line, but there is still no way to resize the
windows by dragging the mouse (still no "handle" under the scroll
bar).

6. With focus still in the righthand window, type `C-x 1' then `C-x 3'
again, and, now with focus in the lefthand window (*scratch*), click
again with mouse-1 in the echo area.  Now the righthand window has a
mode line, and now there is a "handle" under the scroll bar
(graphically denoted by the appearance of `<-|->' in the mode line
when the mouse pointed is over it), and it is possible to resize the
windows by dragging the mouse.

7. Put focus back in the *scratch* window (which lacks a mode line),
type `C-x 1', then `M-: (set-scroll-bar-mode nil)', and then `C-x 3'.
Now there is a thin vertical line separating the two windows, and when
the mouse is over this line or within the fringe to the left of it,
the "handle" appears and it is possible to resize the windows by
dragging the mouse.  (Contrast this with the case of vertical
splitting in 3.)
