I don't understand what you have in mind.  The above commands seem to
do what you want only when ARG is 1.  Or what did I miss?

For scrolling just one window-full, setting next-screen-context-lines
to 1 should do what you want.  For scrolling more than that, I don't
understand how to generalize what you want.
