5285 This is an example of an "atomic group", details of which are given
5286 below. This particular group matches either the two-character sequence

6436 Note that a possessive quantifier can be used with an entire group, for
6443 simpler forms of atomic group. However, there is no difference in the
6444 meaning of a possessive quantifier and the equivalent atomic group,

6894 The first part of the pattern is a DEFINE group inside which a another
