Pretty-print the contents of <object> based on its type.
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

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