	* include/bits/locale_facets.tcc (money_get<>::do_get(...,
	string_type&)): Use find_first_not_of to strip leading
	zeros; if __tmp_units == "0" never prefix it with '-';
	always fail if __tmp_units is empty.
	* testsuite/22_locale/money_get/get/char/10.cc: New.
	* testsuite/22_locale/money_get/get/wchar_t/10.cc: Ditto.
