        The backtrackTo label from the first term in a list of terms is
        being overwritten by processing of subsequent terms.  Changed
        copyBacktrackToLabel() to check for an existing bcaktrackTo label
        before copying and renamed it to propagateBacktrackToLabel() since
        it no longer copies.
