stty fails with a non-obvious error message if it's run on a non-tty
stream, such as a rsh or vi pipeline.

The error message is:
stty: TIOCGETD: Operation not supported

It's immediately obvious to the knowledgable hacker type, but not
exactly comforting to the user who's not native to unix.  It's
especially confusing if there's a stty command in their .cshrc and
it's showing up on rsh output.

(Fixes PR #bin/573)
