patch 8.1.0015: cursor color wrong when closing a terminal window

    patch 8.1.0015: cursor color wrong when closing a terminal window

    Problem:    Cursor color wrong when closing a terminal window, ending up in
                another terminal window. (Dominique Pelle)
    Solution:   Bail out of terminal_loop() when the buffer changes.
                (closes #2942)
