I've been thinking about this. The user at a shell prompt is the only one
who knows exactly what has happened. He knows whether or not the last
command contained a syntax error: he's seen the error message. She is the
only one who knows whether or not she typed ^C, or ^C^C, or ^C RET. He
knows whether or not he suspended the last running job. Why take so much
effort to (imperfectly) figure out and display things you already know?
