This is great news!  As an additional data point, Windows is lagging  
behind with 41 failures (604 pass).  Some aren't important (test-gendoc*  
complaining titles are too short), but some are (some log commands fail  
because of bytes vs str in nturl2path.pathname2url()[1]).  A couple new  
failures seemed to have crept into the list in the last ~150 commits, and  
I think pager tests might be flaky.  Some of the protocol testing seems to  
be picking up an extra trailing '\r':

If there's interest, I should be able to set up a py3 buildbot on a much  
faster Windows 10 system.  The total output is ~130K, so I don't want to  
just post that.
