+        * 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.
