It would be absurd to change Emacs's text model to fit the demands of
a GUI toolkit.  However, we could consider computing the "total size"
for scrolling to include N fictitious final blank lines, N = window

    AFAIK that's what we do for LessTif and Gtk,

Jan, is that what we do for GTK?

Yes,and for Lesstif/Motif. There has been bug reports on this approach. The main confusion seems to be that when a small buffer is used (like the three initial lines in the *scratch* buffer), the scrollbar thumb does not extend to the bottom, since we have added the fictitious lines at the bottom. The assumtion is that if you are seeing the whole buffer, the scroll bar thumb should indicate that by extending from top to bottom.
