        not be combined with any other options or arguments.  See the
        section `BATCH OUTPUT` below for details.
 
+--batch-all-objects::
+       Instead of reading a list of objects on stdin, perform the
+       requested batch operation on all objects in the repository and
+       any alternate object stores (not just reachable objects).
+       Requires `--batch` or `--batch-check` be specified. Note that
+       the objects are visited in order sorted by their hashes.
+
+--buffer::
+       Normally batch output is flushed after each object is output, so
+       that a process can interactively read and write from
+       `cat-file`. With this option, the output uses normal stdio
+       buffering; this is much more efficient when invoking
+       `--batch-check` on a large number of objects.
+
+--allow-unknown-type::
+       Allow -s or -t to query broken/corrupt objects of unknown type.
+
 --follow-symlinks::
        With --batch or --batch-check, follow symlinks inside the
        repository when requesting objects with extended SHA-1
