QA Plan
-------
Try running the scripts locally.  I was calling the bin file directly doing `bin/op`, but if you bundle, it should add the `op` command to your path.

I have tested out a decent number of these already (this PR was created using `pull-request`), so just confirm that the rest are working as expected.
Does this work? How does it know which one you're specifying if they are both optional? Seems like one should be required here and then it would just start with master or whatever the base branch is in github.
