message:
Rewrite display-buffer-alist and display-buffer-normalize-specifiers.
* window.el (display-buffer-alist): Set pop-up-window-min-height
and pop-up-window-min-width in default value. Reported by
Thierry Volpiatto <address@hidden>. New specifier
other-window-means-other-frame.
(display-buffer-macro-specifiers): Comment out entry for
other-window specifier.
(display-buffer-other-window-means-other-frame): New function.
(display-buffer-normalize-specifiers-1): New arguments
buffer-name and label. Treat other-window case specially.
(display-buffer-normalize-specifiers-2): Treat other-window case
specially.
(display-buffer-normalize-specifiers-3): New function.
(display-buffer-normalize-specifiers): Call
display-buffer-normalize-specifiers-3.
