zreplicate does not accurately detect when the transfer is supposed to be local

[Rudd-O]

if the hostname of the sending / receiving side evaluates to the IP address of the machine where the zreplicate transfer is executing, then SSH should be elided altogether for that leg of the transfer.

the idea being that 127.0.0.x or any hostname pointing to an IP address that $HOSTNAME also points to, should be simply interpreted as local transfer.
