It's not completely clear what happens next with this.  Are you hoping 
code churn here has calmed down enough for Jaime or someone else to try 
and look at this more already?  Or should we wait for a new update based 
on the feedback that Heikki and Tom have already provided first, perhaps 
one that proposes fixes for these two test cases?

One general suggestion about the fight with upstream changes you've run 
into here.  Now that you're settling into the git workflow, you might 
consider publishing updates to a site like Github in the future too.  
That lets testing of the code at the point you wrote it always 
possible.  Given just the patch, reviewers normally must reconcile any 
bit rot before they can even compile your code to try it.  That gets 
increasingly sketchy the longer your patch waits before the next 
CommitFest considers it.  With a published git working tree, reviewers 
can pull that for some hands-on testing whenever, even if a merge 
wouldn't actually work out at that point.  You just need to be careful 
not to push an update that isn't self-consistent to the world.  I 
normally attach the best formatted patch I can and publish to Github.  
Then reviewers can use whichever they find easier, and always have the 
option of postponing a look at merge issues if they just want to play 
with the program.
