 -----------------------
 
+GF/01 DEFER rather than ERROR on redis cluster MOVED response.
+     When redis_servers is set to a list of > 1 element, and the Redis servers
+     in that list are in cluster configuration, convert the REDIS_REPLY_ERROR
+     case of MOVED into a DEFER case instead, thus moving the query onto the
+     next server in the list. For a cluster of N elements, all N servers must
+     be defined in redis_servers.
+

       which internalises the check required to safely use the old one, plus
       the allocate and data copy operations duplicated in both (!) of the
