  FreeBSD src repository

  Modified files:
    usr.bin/su           su.c 
  Log:
  It seems when su executes in a shell scripts, there is a timing race,
  sometimes, su will receive a SIGTTOU when parent su tries to set child
  su's process group as foreground group, and su will be stopped unexpectly,
  ignoring SIGTTOU fixes the problem.
