This does not always work, and certainly complicates matters greatly.
Terminal manufacturers seem to be able to come up with the most bizarre
behaviours.  For instance, some terminals distinguish between blanks
and `non blank white space'; some retain display text above and below;
some use absolute cursor addressing and some screen-relative; and so
forth.

It may not be impossible, but it is definitely hard, to use newline
for up-scrolling.
