title: "Cannot update paths and switch to branch at the same time"
body: <p>I sometimes use the <code>checkout -b</code> option to create a new branch, check it out at the same time and set up tracking in one command.</p>
  
  <p>In a new environment, I get this error:</p>
  
  <pre><code>$ git checkout -b test --track origin/master
  fatal: Cannot update paths and switch to branch 'test' at the same time.
  Did you intend to checkout 'origin/master' which can not be resolved as commit?
  </code></pre>
  
  <p>Why does Git not like it? This used to work with the same repo.</p>
