RETRUNNEEDED appears never to be referenced outside of
http.c (and wget.h), and, when returned by gethttp, is
translated by http_loop to RETROK.
+ * url.c (are_urls_equal): Don't call getchar_from_escaped_string
+ if u2 is shorter than u1.
+ (getchar_from_escaped_string): Don't decode reserved characters.
+ Handle illegally appearing '%'s as literal '%'s. Ensure hex
+ digits before attempting to decode.
+ (test_are_urls_equal): Added tests to handle u2 shorter than u1,
+ and %2f not treated the same as /.
+ * spider.c (in_url_list_p): Don't call are_urls_equal if one of
+ them is NULL.
