If somebody is prepared to write a patch to the --rrii task to search for
the right state.txt file to initialise with, then go for it ;-)

While the old date based names were easy to identify, unfortunately they
don't work with replication files which are only approximately aligned with
timestamps.  Initialising the replication is a little annoying due to the
disconnect between timestamp and sequence number, but as Frederik points out
from that point on the replication mechanism is simpler.
