I like your improvements! In particular the config bits which, with all 
evidence, I never do right :-(

Thanks.
Indeed, currently _Impl::_Impl(const char*, size_t) is passed the "C" 
string in order for it to call the underlying locale, but then all the 
information about the individual categories must be extracted from it 
via strtok. This is a pity, since it was available not mangled in 
locale::locale(const char*).

Ciao, Paolo.
