278   (subexp)           capturing group
289                      In negative look-behind, capturing group isn't allowed,
290                      but non-capturing group (?:) is allowed.

388   When we say "backreference a group," it actually means, "re-match the same
389   text matched by the subexp in that group."
391   \n  \k<n>     \k'n'     (n >= 1) backreference the nth group in the regexp
392       \k<-n>    \k'-n'    (n >= 1) backreference the nth group counting
394       \k<+n>    \k'+n'    (n >= 1) backreference the nth group counting
396       \k<name>  \k'name'  backreference a group with the specified name
399   the last group with the name is checked first, if not matched then the

416     Destine a group on the recursion level relative to the referring position.
441   When we say "call a group," it actually means, "re-execute the subexp in
442   that group."
444   \g<n>     \g'n'     (n >= 1) call the nth group
446   \g<-n>    \g'-n'    (n >= 1) call the nth group counting backwards from
448   \g<+n>    \g'+n'    (n >= 1) call the nth group counting forwards from
450   \g<name>  \g'name'  call the group with the specified name
460   * Call by number is forbidden if any named group is defined and
463   * The option status of the called group is always effective.
468 10. Captured group
470   Behavior of an unnamed group (...) changes with the following conditions.
471   (But named group is not changed.)
473   case 1. /.../     (named group is not used, no option)
475      (...) is treated as a capturing group.
477   case 2. /.../g    (named group is not used, 'g' option)
479      (...) is treated as a non-capturing group (?:...).
481   case 3. /..(?<name>..)../   (named group is used, no option)
483      (...) is treated as a non-capturing group.
486   case 4. /..(?<name>..)../G  (named group is used, 'G' option)
488      (...) is treated as a capturing group.
516    + named group                     (?<name>...), (?'name'...)
518    + subexp call                     \g<name>, \g<group-num>
542    + add named group and subexp call.
571      then changes of the capture group status are checked as stop condition.
