The idea is, if you use it with -x (or --xlog), it's for taking a
backup/clone, *not* for replication.

If you use it without -x, then you can use it as the start of a
replica, by adding a recovery.conf.

But you can't do both at once, that will confuse it.

Well, it needs to be included inthe commit, and if I exclude it inthe
posted patch, I'll just forget it in the end :-)
