complex (complex<float>::operator=(float), [...]): Simplify a tad...

2010-09-16  Paolo Carlini  <paolo.carlini@oracle.com>

	* include/std/complex (complex<float>::operator=(float),
	complex<float>::operator+=(float),
	complex<float>::operator-=(float),
	complex<double>::operator=(double),
	complex<double>::operator+=(double),
	complex<double>::operator-=(double),
	complex<long double>::operator=(long double),
	complex<long double>::operator+=(long double),
	complex<long double>::operator-=(long double)): Simplify a tad,
	just forward to the underlying __complex__ T operators, as
	operator*= and operator/= already do.

	* include/std/complex (complex<float>, complex<double>,
	complex<long double>): Simplify spelling of return types, just
	say complex, instead of complex<float>, complex<double>,
	complex<long double>, respectively.
