Actually, I'm running screen under PuTTY right now, and while it does
in fact scrollback, it does _NOT_ scrollback over the currecnt screen
session, but rather it scrolls back to what was on the tty before I
started screen.

Note that the middle command is where I connected to the screen
session.  I suppose that xterm could be made to emulate this behaviour,
but I don't see how usefuel it is.

Scrolled back half-height in my PuTTY session:
