Unless I'm mistaken it seems message is the only variable available for templating commit entries. I was hoping to put together a changelog with a format something like:

[{{sha}}]({{url}}) {{message}} - {{author.name}}

I was wondering if there's a specific reason whycommitMessages() just pulls out the commit message rather retaining the commit object (or a subset of it), which can then pass through the system eventually allowinggenerateCommitsBody() to template on more than just the commit message? If not, is this something that could be added?
