Felix and I met some time before he wrote that blog post, and I explained our C4 process to him. His pull request hack, which I merged into C4 not long after, is neat though github doesn't provide the tools to do it easily.
Was going to suggest the same thing :) I haven't had the sort of success that the OP did, but that PR Hack post def inspired my way of operating! Yay Felix
I'm gonna say you're probably right. I read the same thing years ago, and it was the first thing that popped into my head reading this.
