updated for version 7.3.868
Problem:    When at the hit-return prompt and using "k" while no text has
            scrolled off screen, then using "j", an empty line is displayed.
Solution:   Only act on "k" when text scrolled off screen.  Also accept
            page-up and page-down.  (cptstubing)
