How about this?

static int setup_tracking(const char *new_ref, const char *orig_ref,
                          enum branch_track track)
{
	char key[1024];
	struct tracking tracking;

	if (strlen(new_ref) > 1024 - 7 - 7 - 1)
		return error("Tracking not set up: name too long: %s",
				new_ref);

	memset(&tracking, 0, sizeof(tracking));
	tracking.spec.dst = (char *)orig_ref;
	if (for_each_remote(find_tracked_branch, &tracking))
		return 1;

	if (!tracking.matches && track != BRANCH_TRACK_ALWAYS)
		return 1;

	if (tracking.matches > 1)
		return error("Not tracking: ambiguous information for ref %s",
				orig_ref);

	sprintf(key, "branch.%s.remote", new_ref);
	git_config_set(key, tracking.remote ?  tracking.remote : ".");
	sprintf(key, "branch.%s.merge", new_ref);
	git_config_set(key, tracking.src ? tracking.src : orig_ref);
	free(tracking.src);
	printf("Branch %s set up to track %s branch %s.\n", new_ref,
		tracking.remote ? "remote" : "local", orig_ref);

	return 0;
}
