Cure worse than disease

[Joseph I. Pallas <pallas@Pescadero>]

I made a version of the VGTS that respected the VT100 scroll region on
linefeeds.  It works fine.  However, when I tried to use it with Emacs
on a TOPS-20, I discovered something unfortunate--Emacs would set the
scrolling region to be lines 1-24, because it thought the terminal type
was VT100.  It left the region as 1-24 on exit, but the OS still believed
the terminal had 28 lines, and did its paged-output magic accordingly.

Result: top four lines of every page scroll off the pad.  This, I think,
is not good.

Suggestions?
