        This function is called when we're stripping revision minlink and
        its descendants from the repository.

        We have to remove all revisions with linkrev >= minlink, because
        the equivalent changelog revisions will be renumbered after the
        strip.

        So we truncate the revlog on the first of these revisions, and
        trust that the caller has saved the revisions that shouldn't be
        removed and that it'll readd them after this truncation.
