Do we reliably call promisor-remote.c:promisor_remote_config()? It's called only during promisor_remote_init(), which happens if we call something like promisor_remote_get_direct(), and I guess we call that one unconditionally (e.g. there's no "if (partial_clone) promisor_remote_get_direct();" that I saw in a brief glance) then it's OK.

I saw Taylor's comment about NULL-ness and other than that, this patch looks good to me.
