Thanks a lot for improvements!

Sorry but I can't build pcre2test for Windows with Visual Studio directly
from svn. There are no simple "press and play" possibility to build. Docs
about building by VS are miserly and obscure.

So I'm forced to wait until PCRE 10.34 is out, and after some time after
it download compiled file from
http://www.rexegg.com/pcregrep-pcretest.html.
