I think you lost me here ... :)
How are the two leading bytes (containing the corresponding capturing group
index, as a big endian unsigned integer) considered then?

For Qt, it would be a nice change. I also guess it would be nice under Win32
(where wchar_t is a typedef for unsigned short). I'm not sure about other
potential users (WebKit?), so I let them speak for themselves. :-)
