If one can get the state of scrolling in a window in Elisp one
could solve this in Elisp only since then one could write
a new scroll function on top of the old, and what it would do
is - based on that information - it would either scroll
normally or not call the function at all, if scrolling was
determined not to make any sense.

But I don't know if such data is available on the Lisp side,
if it is, I for one haven't found it ...
