I would say so if having this default_fn made the code more complex, but
here the code is basically

+	if (default_fn)
+		store_credential_file(default_fn, c);

and

-		store_credential(file, &c);
+		store_credential(&fns, &c, fns.items[0].string);

Taking the first element in the list wouldn't change much.

I'm personally fine with both versions.
