hmmm... I should have merged this one first. @KyleKing Could you rebase this PR?

[KyleKing]

I had the fork in a weird state from an interactive rebase trying to fix my default merge tool, but all I needed was git pull --rebase upstream master

I think this should now be ready to merge. Thanks and Happy New Year!
