raw_ostream has an is_displayed() member function that determines if the stream is connected to a console for display or is connected to a file/pipe.  By default, is_displayed() return false, and derived classes like raw_fd_ostream override it.  Because circular_raw_ostream wraps another stream, its result for is_displayed() should be the same as that stream.
