      4 The search range for the NOTs used to end at the start of the match range for
      5 the first DAG in the following DAG group.  Now it ends at the start of the
      6 match range for the entire following DAG group.

     38 The start of the search range for the second or later DAG group used to be
     39 different for its first DAG than its other DAGs.  For the first DAG, it was
     40 the start of the permitted range for the preceding DAG group, and there was a
     41 reordering complaint if the match range was in the first DAG group's match
     42 range.  For the other DAGs, it was the end of the match range for the
     43 preceding DAG group, so reordering detection wasn't possible.  Now, the
     44 first DAG behaves like the others, and so reordering detection is no longer
     45 implemented.  As a result, matches that used to produce the reordering
     46 complaint are now skipped, permitting later matches to succeed.
