+
+       Refine redisplay optimizations to only redisplay *some* frames/windows
+       rather than all of them.
+       * xdisp.c (REDISPLAY_SOME): New constant.
+       (redisplay_other_windows, wset_redisplay, fset_redisplay)
+       (bset_redisplay, bset_update_mode_line): New functions.
+       (message_dolog): Use bset_redisplay.
+       (clear_garbaged_frames): Use fset_redisplay.
+       (echo_area_display): Use wset_redisplay.
+       (buffer_shared_and_changed): Remove.
+       (prepare_menu_bars): Call Vpre_redisplay_function before updating
+       frame titles.  Compute the actual set of windows redisplayed.
+       Don't update frame titles and menu bars for frames that don't need to
+       be redisplayed.
+       (propagate_buffer_redisplay): New function.
+       (AINC): New macro.
+       (redisplay_internal): Use it.  Be more selective in the set of windows
+       we redisplay.  Propagate windows_or_buffers_changed to
+       update_mode_lines a bit later to simplify the code.
+       (mark_window_display_accurate_1): Reset window and buffer's
+       `redisplay' flag.
+       (redisplay_window): Do nothing if neither the window nor the buffer nor
+       the frame needs redisplay.
+       * window.h (struct window): Add `redisplay' field.
+       (wset_redisplay, fset_redisplay, bset_redisplay, bset_update_mode_line)
+       (redisplay_other_windows, window_list): New declarations.
+       * window.c (select_window, Fset_window_start): Use wset_redisplay.
+       (window_list): Not static any more.
+       (grow_mini_window, shrink_mini_window): Use fset_redisplay.
+       * minibuf.c (read_minibuf_unwind): Don't redisplay everything.
+       * insdel.c (prepare_to_modify_buffer_1): Use bset_redisplay.
+       * frame.c (Fmake_frame_visible): Don't redisplay everything.
+       * frame.h (struct frame): Add `redisplay' field.
+       Move `external_menu_bar' bitfield next to other bit-fields.
+       (SET_FRAME_GARBAGED): Use fset_redisplay.
+       (SET_FRAME_VISIBLE): Don't garbage the frame;
+       Use redisplay_other_windows.
+       * buffer.h (struct buffer): Add `redisplay' field.
+       * buffer.c (Fforce_mode_line_update): Pay attention to the `all' flag.
+       (modify_overlay): Use bset_redisplay.
+       * alloc.c (gc_sweep): Don't unmark strings while sweeping symbols.
+
