In the set of ANSI C libraries I wrote for the Alpha Micro, opening a
terminal in unbuffered mode returns single characters without waiting
for a carriage return.  I don't know whether UNIX libraries work this
way or not, but is there any reason they couldn't or shouldn't?  This
doesn't handle echo suppression, of course.  In any case, these things
seem more appropriate for POSIX than for ANSI C.
