commit 8debe47178fd964f1e543d3b669a6f0292f0f07c

    undo: don't run diff between last tid and tid_max
    Diff works on pairs of tids and not on only the first tid passed in to
    the generator.  As a result, there is nothing to do for the last pair of
    tids: the last tid and max_tid refer to the same version.  Avoid running
    the generator in this case.
