output redirection from a compat

[Edward L. Lafferty]

I want to thank those who suggested fixes for this problem. In
particular, the change in the chess binary sent by Steven Haflich of
MIT. I also intend to try the pty suggestion on 4.2.

I have a little curses program that plays chess into a full screen
"board" interractively so you can see the progress of the game. If
anyone wants it I'll put it into net.sources.
