Make CUD more usual
Whether CUD scrolls the screen or not is implementation-dependant.
Applications are not supposed to assume one way or the other, but they
sometimes do, and most implementations do scroll, so let's stick to common
practice.
* console/display.c (handle_esc_bracket): On CUD/VPR, scroll the screen
instead of capping the cursor position.
