If you had commits which both touched my-module/ and also made reference to other files outside of my-module/, then you may also want to clean those up. If that's something you can write code to do (perhaps because the commit messages were regular, or you are an expert at parsing and rewriting natural language programatically), then the --message-callback suggested by Son could help you out. That sounds difficult to me, because I don't know how to even identify such commits without having a human being read every single one. But it sounded to me like most of the commit messages you didn't want were ones that just touched paths outside of your selected module, in which case the simple path filtering I suggested above would clear those all out for you.
