Cbreak or not Cbreak, that is the question ...

But that wont get the same thing as turning CBREAK on. The read() call
still wont return until a full line has been typed. There is no call in Unix
like ci() in DeSmet C. ci() can be simulated by going into CBREAK mode,
reading one character, and then going back to normal. A better idea might
be to rework the program to use CBREAK mode at all times.
