locale_facets.tcc (money_get::do_get(string)): Check for zero-length negative sign before adding it to output string.

2002-01-11  Benjamin Kosnik  <bkoz@redhat.com>

	* include/bits/locale_facets.tcc (money_get::do_get(string)):
	Check for zero-length negative sign before adding it to output
	string.
	(money_get::do_get(long double)): Return beg.
	* testsuite/22_locale/money_get_members_char.cc (test02): Add
	iterator checks.
	* testsuite/22_locale/money_get_members_wchar_t.cc: Same.
