basic_string.h (operator+=(initializer_list<>), [...]): Forward to the append overload taking a const CharT* pointer and a size...

2009-10-14  Paolo Carlini  <paolo.carlini@oracle.com>

	* include/bits/basic_string.h (operator+=(initializer_list<>),
	append(initializer_list<>)): Forward to the append overload taking
	a const CharT* pointer and a size, thus avoiding instantiating
	unnecessarily in the built library the overload taking a pair of
	iterators.
	(operator=(initializer_list<>), assign(initializer_list<>)): Likewise
	for assign.
	(insert(iterator, initializer_list<>): Likewise for insert.
