  SVN rev 214281 on 2010-10-24 17:06:49Z by jilles
  
  sh: Change ! within a pipeline to start a new pipeline instead.
  
  This is how ksh93 treats ! within a pipeline and makes the ! in
    a | ! b | c
  negate the exit status of the pipeline, as if it were
    a | { ! b | c; }
  
  Side effect: something like
    f() ! a
  is now a syntax error, because a function definition takes a command,
  not a pipeline.
  
  Exp-run done by:        pav (with some other sh(1) changes)
