locale_facets.tcc (time_get::_M_extract_via_format): Use narrow to get from __format[__i] a char __c representing a formatting code...

2003-12-17  Paolo Carlini  <pcarlini@suse.de>

	* include/bits/locale_facets.tcc (time_get::_M_extract_via_format):
	Use narrow to get from __format[__i] a char __c representing a
	formatting code, don't use it to compare *__beg to __format[__i].
	* testsuite/22_locale/time_get/get_date/wchar_t/4.cc: New.
