Is there have data consistency check function?

I guess they meant to run the checksums phase and show the results (I'd say "different blocks" sum in normal mode and possibly a more detailed resport in verbose) without actually transferring anything.
Maybe it could be useful to print the top hash of both src and tgt in verbose mode.
