Get argument list for meth:`subprocess.Popen()` to run rsync.

        :param rsync_options:
            any additional arguments to pass to rsync, useful if you
            want to pass '-a'
        :returns:
            argument list to pass as the first argument to subprocess.Popen()

        .. note::
            you must call :meth:`connect()` at least once
            before calling this method.

        This method returns the ``args`` argument (first argument) to
        subprocess.Popen() required to rsync something over to the phablet
        device. You can use it to construct your own connections, to intercept
        command output or to setup any additional things that you may require.
