When autoland commits, it includes the actual commit message, but appends "\nApproved by Juju Gui Bot, Aaron Bentley".

For many projects, short (i.e. one-line) commit messages are a virtue, because they allow more to fit on the screen. In Launchad, the convention was to prefix the message with "[r=juju-gui-bot,abentley]".
