I don't think this command-line "<url>" mode works at all. Your underlying function can handle either stdin or arguments:

...but the new caller rejects them before we get there:

So you'd want at least:
diff --git a/t/helper/test-submodule.c b/t/helper/test-submodule.c
index da89d265f0..6b964c88ab 100644
--- a/t/helper/test-submodule.c
+++ b/t/helper/test-submodule.c
@@ -88,8 +88,6 @@ static int cmd__submodule_check_url(int argc, const char **argv)
 	};
 	argc = parse_options(argc, argv, "test-tools", options,
 			     submodule_check_url_usage, 0);
-	if (argc)
-		usage_with_options(submodule_check_url_usage, options);
 
 	return check_submodule(argc, argv, check_submodule_url);
 }

but then that reveals another mismatch. In check_submodule() above we
expect argv[0] to be uninteresting (i.e., the name of the program), but
parse_options() will already have thrown it away. So we silently fail to
check the first option (which is especially bad since the only output is
the exit code, and thus the skipped one looks the same as one that
validated correctly).

All of this is inherited from the existing check_name() code, which I
think has all of the same bugs. The test scripts all just use the stdin
mode, so they don't notice. It's not too hard to fix, but maybe it's
worth just ripping out the unreachable code.
