Well, I had no involvement in the windows registry reading stuff, and it is relatively new.  And, as issue 10551 indicates, a bit controversial.  (issue 15199 is a different bug, in python's own internal table).

Can you run that diff again and use the '-u' flag?  The -u (universal) format is the one we are used to working with.  The one you posted still lets us read the changes, though, which is very helpful.
