Annoying.  Could be patched in rsync, though.  I bet that
Wayne would consider an option to do this.

Wouldn't matter except on the first transfer, since on the target 
would have the same junk in the empty areas.

Might actually take more time to transfer - even with compression some
representation of the nul bytes has to be sent, but i bet it would be
noise in the total transfer.  *would* mean lots more disk writes, once
to put in all the nuls in the first place and once to put them in on
the target.
