[PATCH] http: inform about alternates-as-redirects behavior




It is disconcerting for users to not notice the behavior
change in handling alternates from commit cb4d2d35c4622ec2
("http: treat http-alternates like redirects")

Give the user a hint about the config option so they can
see the URL and decide whether or not they want to enable
http.followRedirects in their config.
