facepalm - a little mercurial extension

I have been using Mercurial for a few months now and I love it. In particular I love the way it separates the act of committing code from inflicting it on everybody else! It is also extensible and I have written a little python extension called facepalm. This will search the changes you are about to commit for common "gotchas!" such as leaving in mercurial-inserted diff text or my personal weakness - commenting out Ignore unit tests and forgetting to comment back in the Ignore attribute causing the build to fail! D'oh! Facepalm!
