Well, it still behaves the same for me in xterm. vim overwrites what is
in the terminal, it doesn't push it into the scrollback.
There is no way for any application to control what the terminal keeps
around in the scrollback, it's entirely up to the terminal. Well, aside
from the "clear scrollback" escape sequence on the Linux console.
Whatever configuration you have must mean that whatever screen uses to
clear the terminal usually pushes things into the scrollback, if we can
figure out what that is and it isn't too complicated we might be able to
do it in tmux, but it will not work in all cases and definitely not with
panes.
I'm not wild about the idea of using a bunch of newlines instead of
clear in terminfo. If I can reproduce it would help... I'll try rxvt if
I have time when I get home.
Did you try xterm itself? TERM is set to xterm?
Can you run screen inside script, do ls -la so it scrolls then run vim,
then exit and send me the typescript file?
