    patch 8.0.0996: Mac: t_RS is echoed on the screne in Terminal.app

    Problem:    Mac: t_RS is echoed on the screne in Terminal.app.  Even though
                $TERM is set to "xterm-256colors" it cannot handle this xterm
                escape sequence.
    Solution:   Recognize Terminal.app from the termresponse and skip sending t_RS
                if it looks like Terminal.app.
