+ object-format
+~~~~~~~~~~~~~~~
+
+The server can advertise the `object-format` capability with a value `X` (in the
+form `object-format=X`) to notify the client that the server is able to deal
+with objects using hash algorithm X.  If not specified, the server is assumed to
+only handle SHA-1.  If the client would like to use a hash algorithm other than
+SHA-1, it should specify its object-format string.
