- Revise previous patches of the same purpose by fixing
*) grep <PA> | not grep <PB> semantically is not the same as
CHECK: <PA>{{^<PB>.*$}} as the former will check all occurrences of <PA>
while the later only check the first match. As the result, CHECK needs
putting in all place where <PA> occurs.
*) grep <PA> | count <N> needs a final CHECK-NOT of the same pattern.
(As 'CHECK-<N>' is proposed for discussion, converting 'grep | count <N>'
where N > 1 is postponed.)
