push over http: server side authorization support. new hgrc entries allow_push, deny_push, push_ssl control push over http. allow_push list controls push. if empty or not set, no user can push. if "*", any user (incl. unauthenticated user) can push. if list of user names, only authenticated users in list can push. deny_push list examined before allow_push. if "*", no user can push. if list of user names, no unauthenticated user can push, and no users in list can push. push_ssl requires https connection for push. default is true, so password sniffing can not be done.
