  SVN rev 196578 on 2009-08-27 07:11:47Z by brian
  
  MFC: When ``ppp -direct'' is invoked by a program that uses pipe(2) to
       create stdin and stdout, don't blindly try to use stdin as a bi-directional
       channel.  Instead, detect the pipe and set up a special exec handler
       that indirects write() calls through stdout.
  
       This fixes the problem where ``set device "!ssh -e none host ppp
       -direct label"'' no longer works with an openssh-5.2 server side as
       that version of openssh ignores the USE_PIPES config setting and
       *always* uses pipes (rather than socketpair) for stdin/stdout channels.
