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)
