title: Show which git tag you are on?
body: <p>I'm having trouble finding out which tag is currently checked out.</p>
  
  <p>When I do:  </p>
  
  <pre><code>git checkout tag1
  git branch
  </code></pre>
  
  <p>I can't seem to find out which tag I'm on. It only logs:</p>
  
  <pre><code>* (no branch)
  master
  </code></pre>
  
  <p>Is it possible to find out which tags are checked out? In the above example, this would be <code>tag1</code>.</p>
