Yes, but we do a delta calculation on the client that's sent to the server,
even in ra_local. Then, the repository recalculates the delta,
possibly against another revision to store it in the FS. If you have
a local epository, or are on a LAN, you might want to trade bandwidth
against speed in another way than you want over a WAN. There may also
be other optimization possibliities, depending on R layer and so on.
