I take it back, I just can't read terminfo's (imagine that).  I added this
code to vt.c,  I'll put it in the next wrap.

I notice that there are a bunch of improvements in vt with
this update.  I want to thank whoever did all that work (Russ,
I think?).  But I noticed that some garbage was being left on
my screen while scrolling in mutt.  Although, strange stuff
still goes on once in a while, most of the problem seemed to
disappear with the following change to vt.c:

/mnt/wrap/sys/src/cmd/vt/vt.c:581 c /sys/src/cmd/vt/vt.c:581
< 								clear(Rpt(pt(0, 0), pt(x, ymax+1)));
---
> 								clear(Rpt(pt(0, 0), pt(xmax+1, y)));

The code is supposed to clear from the first character on the
screen up through the current position.  As it was, this line
would clear everything to the left of the current position and
the next would clear everything on the current line up to the
current position.  I think the line should really clear
everything above the current position, and at least mutt seems
to work a little better that way.
