The 4.3bsd version of the rlogin protocol transmits window size changes.
Rlogin sets up a SIGWINCH handler and sends an out-of-band message with the
new window size.  When rlogind receives this control sequence it performs
an ioctl() of the pty to set the window size, which causes the process on
the other end of the pty to get a SIGWINCH.
