For some reason, hotfix is failing to merge regardless of using `stable` or `dev_branch`.
```
> h merge                                                                                                                              
> git fetch

        from /home/rchoudhury/projects/git-scripts/bin/hotfix:73:in `<main>'
```
This merge was done on a [test repo](https://github.com/brotatos/test-hotfix).
