+;; buffers from a list summarizing their state.  A good way to browse

+
+;;; Change Log:
+
+;; Merged by esr with recent mods to Emacs 19 buff-menu, 23 Mar 1993
+;;
+;; Modified by Bob Weiner, Motorola, Inc., 4/14/89
+;;
+;; Added optional backup argument to 'Buffer-menu-unmark' to make it undelete
+;; current entry and then move to previous one.
+;;
+;; Based on FSF code dating back to 1985.
+
+;;; Code:
+ 
+;;;Trying to preserve the old window configuration works well in
+;;;simple scenarios, when you enter the buffer menu, use it, and exit it.
+;;;But it does strange things when you switch back to the buffer list buffer
+;;;with C-x b, later on, when the window configuration is different.
+;;;The choice seems to be, either restore the window configuration
+;;;in all cases, or in no cases.
+;;;I decided it was better not to restore the window config at all. -- rms.
+
+;;;But since then, I changed buffer-menu to use the selected window,
+;;;so q now once again goes back to the previous window configuration.
+
+;;;(defvar Buffer-menu-window-config nil
+;;;  "Window configuration saved from entry to `buffer-menu'.")
+
+; Put buffer *Buffer List* into proper mode right away
+; so that from now on even list-buffers is enough to get a buffer menu.
