title: How to "revive" git blame history
body: <p>I find myself in a precarious situation.</p>
  <p>I work on refactoring a big, existing codebase. I decided to comment out some tests and enable them gradually as I adapt the code. Unfortunately, I committed the commenting-out and now the git blame history of a complete test module shows me as the author of the last change. My only committed contribution to this code is two commits (commenting and uncommenting) - unfortunately the first ones comes with changes in other places I want to keep.</p>
  <p>I am not knowledgeable in git enough to know if there is a relatively easy way to correct the git history to showing the author of the previous state of the code (prior to my commenting out).</p>
  <p>Is starting from scratch my only option?</p>
