Yeah, I wasn't sure about the commit flag either! I opted to add the feature using a `--commit` flag with no arguments, and the default remaining to not commit, much like `fetch` itself.

Then, I made the automatic commit messages reflect a style that looked like git's standard automatic commit messages, with summaries for larger commits. Though upon reflection, maybe a list of file changes or updates would be more in-line with git's style.

Maybe that's close enough.
