- define regExp::results_type using SubStrings container for handling
groups. This makes a later shift to std::smatch easier, but changes
the regExp API for matching with groups. Previously had list element
0 for regex group 1, now list element 0 is the entire match and list
element 1 is regex group 1.
Old:
List<std::string> mat;
if (re.match(text, mat)) Info<< "group 1: " << mat[0] << nl;
New:
regExp::results_type mat;
if (re.match(text, mat)) Info<< "group 1: " << mat.str(1) << nl;
