The patch is correct. The code is tricky so I'm not surprised you wanted 
another pair of eyes. The attached patch is a very minor tweak of your 
patch that made it a bit easier for me to follow. I resisted the 
temptation of cleaning up the surrounding code to make it more readable.

I like the idea of putting this into the emacs-25 branch. (Or your 
patch; doesn't really matter.)
