+       Be more careful if selected window shows the buffer other than current,
+       use window_outdated only if this is not so.  This change should also
+       address some weird issues discussed in Bug#13012.
+       * window.h (window_outdated): New prototype.
+       * window.c (window_outdated): Now here.  Convert from static and
+       always assume window's buffer.
+       (Fwindow_end, Fwindow_line_height): Use it.
+       * xdisp.c (reconsider_clip_changes): Remove prototype, drop 2nd arg
+       and always assume window's buffer.
+       (redisplay_window): Adjust user.
+       (redisplay_internal): Call to reconsider_clip_change once and
+       check whether mode line should be updated only if selected window
+       shows current buffer.
+       (run_window_scroll_functions): Use eassert for debugging check.
+       (Fmove_point_visually, note_mouse_highlight): Use window_outdated.
