[Bug c++/16169] New: -Weffc++ item 15 improvements

["bkoz at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

It would be nice to have operator= return a function that returns a refernce to
*this.

Right now, this warns. See the differences between basic_string.h's
std::string::operator= between 3.3.x and 3.5.x.


      basic_string&
      operator=(const basic_string& __str) { return this->assign(__str); }


vs.

      basic_string&
      operator=(_CharT __c) 
      { 
	this->assign(1, __c); 
	return *this;
      }
