I just tried pushing for the first time since installing the new pre-push hook that runs `make authenticate`.
This failed with the following error: Git error: cannot locate remote-tracking branch 'keyring' However, `git branch --all` includes "remotes/origin/keyring". After I did `git checkout origin/keyring`, it worked. Let's update the manual section Commit Access with the recommended way to make this branch accessible to `make authenticate`. Maybe it should even do it automatically?
