It uses a "rolling" checksum, so that it can actually find byte-level
changes, insertions, deletions. There's a block size for how big a chunk
to start with, but then it works within those to figure out where to make
the changes. It's hyper-efficient. The thing about transferring whole
files (-W option) is actually an override of the default, mostly to keep
it from wasting time reading everything twice over NFS, or for any case
where you know up front that you're better off just sending the whole
thing if you have to read it at all (time or size mismatch).
