title: What's the git equivalent of "svn update -r"?
body: <p>I'm a recent git convert. It's great to be able to use git-svn to keep my branches locally without disturbing the svn server. There was a bug that existed in the latest version of the code. I wanted to establish a time when it worked so that I could use git bisect. I couldn't find the right command to move back in time. Thanks.</p>
