+Apply the following patch on top of the previous two to allow scrolling
+the backbuffer using MouseWheel only when not in MODE_ALTSCREEN.
+This way when e.g. viweing files in less the content is being scrolled instead of the
+scrollback buffer. Consequently the Shift modifier for scrolling is not needed anymore.
