+ * with "https://other.example.com/foo.git/info/refs". We would want the

+ *
+ * Note that this assumes a sane redirect scheme. It's entirely possible
+ * in the example above to end up at a URL that does not even end in
+ * "info/refs". In such a case we simply punt, as there is not much we can
+ * do (and such a scheme is unlikely to represent a real git repository,
