From: Richard M. Stallman <rms@prep>
The VT100 termcap string here expects the first
argument to be the 0-origin line number of the
first line in the scrolling region,
and the second argument to be the 0-origin
line number of the first line beyond the scrolling region.

Therefore, GNU Emacs uses that convention.
