+       * window.c (window_scroll_pixel_based): Fix scrolling in the wrong
+       direction if window height was smaller than next-screen-context-lines.
+       Now always scroll at least one line in the requested direction.
+       Ensure that we actually do scroll backwards when requested to do so.
