buffering; this is much more efficient when invoking
`--batch-check` on a large number of objects.
+--unordered::
+ When `--batch-all-objects` is in use, visit objects in an
+ order which may be more efficient for accessing the object
+ contents than hash order. The exact details of the order are
+ unspecified, but if you do not require a specific order, this
+ should generally result in faster output, especially with
+ `--batch`. Note that `cat-file` will still show each object
+ only once, even if it is stored multiple times in the
+ repository.

--allow-unknown-type::
Allow -s or -t to query broken/corrupt objects of unknown type.
