// between them copies a key onto itself and then deletes it. The scheme and
// credentials are dropped, a missing port or db takes the default, and a
// ?db= query wins over the path as it does in redis-py.
// shortcut: only the loopback names are folded; a DNS name and its IP still
// read as two servers. Resolve them if two such mounts appear.
