        * src/locale.cc (locale::locale(const char* __name)): Consolidate
        name setting. Add checks for NULL __name pointers. Remove calls to
        _S_initialize() as initial locale initialization can either be
        assumed, or needs to be made consistent throughout locale
        constructors.
        (locale::locale(const locale& __other, const char* __name,
        category __cat): Add checks for NULL name. Add checks for
        assignment to self.
        * src/localename.cc (locale::_Impl:: _Impl(const _Impl& __other,
        const string& __name, category __cat, size_t __refs)): Set correct
        name, has_name values.
        * testsuite/22_locale/ctor_copy_dtor.cc (test01): More tests.
        * docs/22_locale/locale.html: New file, more unfinished docs...
