Makes total sense!

Done! Changed regex to C++11 regexp and added documentation reference in glib.


P.S. Weirdly enough, I couldn't convert to and from an std::string to
GooString.
In line 522, instead of: std::string pdfsubver = pdfSubtypeVersion->toStr();
I had to go with:

std::string pdfsubver(pdfSubtypeVersion->getCString(), // Which immitates the 
                      pdfSubtypeVersion->getLength()); // toStr() declaration.
Upon compilation it was throwing an error that toStr is not member of Class
GooString.

And in line 555 instead of GooString *conf = new GooString(match.str(3));
I went with: GooString *conf = new GooString(match.str(3).c_str());

However, performance-wise the two versions are the same.
