Starting from the original up to this point, the code structure of
this function have bothered me quite a bit because I would expect

	if (depth == INFINITE_DEPTH && !is_repository_shallow()) {
		for (i = 0; i < shallows->nr; i++) {
			struct object *object = shallows->objects[i].item;
			object->flags |= NOT_SHALLOW;
		}
	} else {
		struct commit_list *result;
		result = get_shallow_commits(&want_obj, depth,
					     SHALLOW, NOT_SHALLOW);
		send_shallow(result);
		free_commit_list(result);
	}
	send_unshallow(shallows);
	packet_flush(1);

would be easier to understand.  The function seems to be reshaped
further in the series, so let's keep reading...
