locale_facets.tcc (num_get<>::_M_extract_float, [...]): If appropriate, call reserve on the __tmp_gruping string.

2004-02-27  Paolo Carlini  <pcarlini@suse.de>

	* include/bits/locale_facets.tcc (num_get<>::_M_extract_float,
	num_get<>::_M_extract_int, money_get<>::_M_extract): If appropriate,
	call reserve on the __tmp_gruping string.
	(num_get<>::_M_extract_float): Don't append unnecessarily a
	char() to the returned string.
	* include/bits/locale_facets.tcc: Trivial reformattings.
