sys.stdin is : buffered and line oriented.
What is your operating system ? Under unix sys.stdin (and C stdin
stream) are managed by a driver which expect you can somewhat modify
the line you want to send to the system. (POSIX normalized)
  If you want a fine control, you can use curses (Unix) or build your
  solution based on getchar (or is it getch() ?) on windows/dos.
