locale_facets.tcc (num_get<>::_M_extract_float): Cache *__beg in __c when parsing exponent sign too.

2004-10-28  Paolo Carlini  <pcarlini@suse.de>

	* include/bits/locale_facets.tcc (num_get<>::_M_extract_float):
	Cache *__beg in __c when parsing exponent sign too.
	(num_get<>::do_get(..., bool&)): Cache *__beg.
	(money_get<>::_M_extract)): Likewise, in money_base::value.
