Currently the following layers are planned: 1. default global behavior 2. old user settings 3. application specifiers 4. new user specifiers We should keep the old mess in 2 for backward-compatibility and design a new clean and simply way to specify 3 and 4, so we don't need to merge new specifiers with old user settings in 2, because new specifiers just override the old user settings. > would then become > > (defun message-mail-other-window (&optional to subject) > "Like `message-mail' command, but display mail buffer in another window." > (interactive) > (unless (message-mail-user-agent) > (let ((pop-up-windows t) > (special-display-buffer-names nil) > (special-display-regexps nil) > (same-window-buffer-names nil) > (same-window-regexps nil)) > (message-pop-to-buffer (message-buffer-name "mail" to) 'other-window))) > > for approximately as long as how we are supporting the old code. Why wouldn't `display-buffer' prefer new settings in the `SPECIFIERS' arg over the old settings in `same-window-regexps' etc.? IOW, when the `SPECIFIERS' arg is `other-window' then `display-buffer' should ignore the values of `same-window-regexps' etc.
