	* include/bits/locale_facets.tcc (num_get<>::_M_extract_float):
	Evaluate *__beg the exact strict minimum number of times; likewise
	for __beg != __end; in the main parsing loop, call ++__beg in two
	places only. The former is also a correctness issue, because,
	according to the standard (22.2.2.1.2, Stage 2), 'in' shall be
	dereferenced only one time for each increment.
