title: How can I completely remove a file from a git repository?
body: <p>I noticed recently that the project files my text editors use (along with some other junk) got added the git repository for the project.  Since they aren't actually part of the project, I'd like to remove them, but <code>git rm</code> doesnt remove the old versions from the repository, and I couldnt find anything else that looks promising.</p>
