	* include/bits/stl_algo.h (search(_ForwardIterator1,
	_ForwardIterator1, _ForwardIterator2, _ForwardIterator2)): Simplify
	general case loop to a for(;;).
	(search(_ForwardIterator1, _ForwardIterator1, _ForwardIterator2,
	_ForwardIterator2, _BinaryPredicate)): Likewise; remove redundant
	inner loop.
