This command can be used to optimize storage of references. For a RefDirectory database, it packs non-symbolic, loose refs into packed-refs. By default, only the references under '$GIT_DIR/refs/tags' are packed. The '--all' option can be used to pack all the references under '$GIT_DIR/refs'. For Reftable, all refs are compacted into a single table. Change-Id: I92e786403f8638d35ae3037844a7ad89e8959e02
