+
+;; Edit, delete, or change attributes of all currently active Emacs
+;; buffers from a list summarizing their state.  A good way to browse
+;; any special or scratch buffers you have loaded, since you can't find
+;; them by filename.  The single entry point is `list-buffers',
+;; normally bound to C-x C-b.
+
+;;; Change Log:
+
+;; Buffer-menu-view: New function
+;; Buffer-menu-view-other-window: New function
 
+;; 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

+;;; 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.
