FYI, here is a github nugget from the scipy people: -------- Original Message -------- Subject: Re: [SciPy-Dev] Used "Automatic Merge" on my github pull request...

If so, how? (The git book is by my side, but I suspect an answer will show up here faster than I can find it.) No, it's public now so you shouldn't touch it anymore. That button is very pointless - best to ignore it. Ralf
