GNU Emacs 22.1.1 (i386-mingw-nt5.1.2600) of 2007-06-02 on RELEASE
Use split-window-vertically once and split-window-horizontally twice to
create a frame that is split into 4 approximately equal sections (2 x
2).
Display a different buffer in each of the 4 windows.
Move the cursor to anywhere in the lower-right window.
Use eval-expression to execute the following expression:
(let* ((edges (window-edges))
(x (first edges))
(y (1- (second edges))))
(window-at x y))
Logically, this should return the upper-right window, but it actually
returns the upper-left window.
Possibly related to this bug, execute the following expression with the
cursor in any window:
(let* ((edges (window-edges))
(x (first edges))
(y (second edges))
(window (selected-window)))
(coordinates-in-window-p (cons x y) window))
Logically this should return (0 . 0) but it actually returns
'left-fringe.
Execute the following expression with the cursor in the lower-right
window:
(let* ((edges (window-edges))
(x (first edges))
(y (1- (second edges)))
(window (window-at x y)))
(coordinates-in-window-p (cons x y) window))
It returns 'vertical-line when it should really return 'mode-line. The
same expression evaluated with the cursor in the lower-left window
returns 'mode-line as it should.
