  Modified files:
    usr.bin/xargs        xargs.1 
  Log:
  o The -s limit is ARG_MAX - 4K, not ARG_MAX - 2K.
  o Mention that the current environment is part of the -s calculation.
  o Add a BUGS section that warns against executing a program that increases
    the size of the argument list or the size of the environment.
  
    I have wondered for a while what the difference is between
  
      get a big list | xargs sudo command
  
    which fails and
  
      get a big list | sudo xargs command
  
    which succeeds.  The answer is that in the first case, sudo expands
    the environment and pushes the amount of data passed into execve over
    the E2BIG threshold.
