 --prune=<date>::
        Prune loose objects older than date (default is 2 weeks ago,
        overridable by the config variable `gc.pruneExpire`).
-       --prune=all prunes loose objects regardless of their age and
+       --prune=now prunes loose objects regardless of their age and
        increases the risk of corruption if another process is writing to
        the repository concurrently; see "NOTES" below. --prune is on by
        default.
