Sorry, it was wrong. It should be as follows.
s0: The position set is none.
s1: The position set is 1:a
s2: The position set is 1:a 2:CSET
s3: The position set is 2:CSET 3:b (accepted)
s4: The position set is 2:CSET
1 accccccccccccccccccccccccccccccccccccccc
^ s1
1 accccccccccccccccccccccccccccccccccccccc
^ s4
1 accccccccccccccccccccccccccccccccccccccc
^ s4
......
1,000,000 cccccccccccccccccccccccccccccccccccccccb
^ s4
1,000,000 cccccccccccccccccccccccccccccccccccccccb
^ s3 accepted
Then re-searched with the superset because matched on multi-lines.
1,000,000 cccccccccccccccccccccacccccccccccccccccb
^ s0
1,000,000 cccccccccccccccccccccacccccccccccccccccb
^ s1
1,000,000 cccccccccccccccccccccacccccccccccccccccb
^ s4
1,000,000 cccccccccccccccccccccacccccccccccccccccb
^ s4
1,000,000 cccccccccccccccccccccacccccccccccccccccb
^ s3 accepted
s0: The position set is none.
s1: The position set is 1:a
s2: The position set is 1:a 2:ANYCHAR
s3: The position set is 2:ANYCHAR 3:b (accepted)
s4: The position set is 2:ANYCHAR
1,000,000 cccccccccccccccccccccacccccccccccccccccb
^ s1
1,000,000 cccccccccccccccccccccacccccccccccccccccb
^ s4
1,000,000 cccccccccccccccccccccacccccccccccccccccb
^ s0 rejected
