Single char input using getchar()

There's nothing wrong with using getchar for single character
input.  The stdio package treats terminals differently than it
does other devices.  Terminal I/O will not be buffered by getchar
or putchar or any other stdio routine unless you request buffering
with setbuf().  The only buffering you have to worry about is
that controlled by ioctl.
