will make the body of the chosen window 40 columns wide. For the

+*** 'display-buffer' provides more options for using an existing window.
+The display buffer action functions 'display-buffer-use-window' and
+'display-buffer-use-least-recent-window' now honor the action alist
+entry 'window-min-height' as well as the entries listed below to make
+the display of several buffers in a row more amenable.
+
++++
+*** New buffer display action alist entry 'lru-frames'.
+This allows to specify which frames 'display-buffer' should consider
+when using a window that shows another buffer.
+
++++
+*** New buffer display action alist entry 'lru-time'.
+'display-buffer' will ignore windows with a use time higher than that
+when using a window that shows another buffer.
+
++++
+*** New buffer display action alist entry 'bump-use-time'.
+This has 'display-buffer' bump the use time of any window it returns,
+making it a less likely candidate for displaying another buffer.
+
++++
+*** New buffer display action alist entry 'window-min-width'.
+This allows to specify a minimum width of the window used to display a
+buffer.
