    That may be more efficient on an ascii terminal (I doubt it), but on a
    bitmapped display, it is always ALWAYS cheaper to clean up a single line
    that to scroll the entire window all over the place.

    Below are two functions, (smooth-scroll-up) and (smooth-scroll-down)
    that solve the problem without trying to hack the update optimizer.

Yargh!  Why don't you fix the padding specifications in your termcap
(and solve the problem *everywhere*), rather than putting information
about the display in scroll-up and scroll-down?
