Make pt-table-sync output exact diffs instead of queries

Registered by Mrten

Some time ago, I wrote a script to show me the exact differences between master and replication slave based on the checksum table generated by mk-table-sync. I did this so I could figure out what queries on the master could have caused these differences in replication (which worked out).

Now, I'm in the process of upgrading all servers to 5.5 and I've noticed differences in the replication from a 5.1 to a 5.5 server, so I figured I'd dust off the script so see what it could show me. So I spent today fixing it up because of the changed checksum table format and while doing that it occurred to me that pt-table-sync could also output the exact differences between master and slave, because I suppose it already has all information.

So here's the wistlist request: Could pt-table-sync --print be made to output more than queries?
