title: Git checkout another branch
body: <p>I run:</p>
  
  <pre><code> git checkout mygithub/master
  </code></pre>
  
  <p>but for some reason, running 'git status' shows "not currently on any branch". Running:</p>
  
  <pre><code> git checkout master
  </code></pre>
  
  <p>and then <code>git status</code>, says that I'm now on branch master. Now I want to switch to another branch. Running <code>git checkout anotherbranch</code> works, but <code>git status</code> says I am still on branch 'master'. What am I doing wrong?</p>
