The shell should handle tty modes along with job control

[Tom Christiansen]

I agree that this is the shell's prerogative.

The (t)csh I've used for the last 5 years or so has always 
done pretty much the right thing with modes.  That is, it restores
your tty to the state it was in before calling the program.  It
does seem to know to do the right thing with stty changes, although
I haven't looked to see how it does that.
