patch 8.2.0773: switching to raw mode every time ":" is used

    patch 8.2.0773: switching to raw mode every time ":" is used

    Problem:    Switching to raw mode every time ":" is used.
    Solution:   When executing a shell set cur_tmode to TMODE_UNKNOWN, so that the
                next time TMODE_RAW is used it is set, but not every time.
