        Delete the pack-files that are tracked  by the MIDX file, but
        have no objects referenced by the MIDX. Rewrite the MIDX file
        afterward to remove all references to these pack-files.

<p>
        Create a new pack-file containing objects in small pack-files
        referenced by the multi-pack-index. If the size given by the
        <code>--batch-size=&lt;size&gt;</code> argument is zero, then create a pack
        containing all objects referenced by the multi-pack-index. For
        a non-zero batch size, Select the pack-files by examining packs
        from oldest-to-newest, computing the "expected size" by counting
        the number of objects in the pack referenced by the
        multi-pack-index, then divide by the total number of objects in
        the pack and multiply by the pack size. We select packs with
        expected size below the batch size until the set of packs have
        total expected size at least the batch size. If the total size
        does not reach the batch size, then do nothing. If a new pack-
        file is created, rewrite the multi-pack-index to reference the
        new pack-file. A later run of <em>git multi-pack-index expire</em> will
        delete the pack-files that were part of this batch.
