keep-cache-if-not-found vs. new redirects

Gentlemen,
# [<URL-SPEC>] keep-cache-if-not-found = yes | no
#         If the remote server replies with an error message or a redirection
#         while there is a cached version with status 200 the previously cached
#         version should be kept (default=no).
should be divided into two cases, "gone" and "302 redirect", otherwise
if I use "yes", online there I am browsing the new location, but
later offline, there I am browsing the old location.
