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.
(test_are_urls_equal): Added tests to handle u2 shorter than u1,
and %2f not treated the same as / (latter currently fails).
* spider.c (in_url_list_p): Don't call are_urls_equal if one of
them is NULL.
