Include the first commit in the first release made

The proper way to do it is to run it like this:

```shell
$ git log --oneline HEAD
```

...i.e. specify only one parameter to `git log`. That way, it means "all entries from the root(s) up to HEAD".

Right now we _always_ include the "to" and "from" revision, which is why the first commit gets excluded. Not a major issue, but a bit annoying it is.
