+Subject: Properly re-implement userinfo parsing (rfc2396)
+
+* src/url.c (url_skip_credentials): Properly re-implement userinfo parsing (rfc2396)
+
+The reason why the implementation is based on RFC 2396, an outdated standard,
+is that the whole file is based on that RFC, and mixing standard here might be
+dangerous.
