title: Unknown tag return by git describe tags command
body: <p>I am on a specific branch on my project and my git commit sha is:</p>
  
  <pre><code>▶ git rev-parse HEAD                                 
  66465022d6f2885bf38d71bed6b56da5b3b163b3
  </code></pre>
  
  <p>Here are all my tags</p>
  
  <pre><code>▶ git tag
  cluster_command
  false_tag
  test
  </code></pre>
  
  <p>However, the <code>git describe --tags</code> returns something unexpected:</p>
  
  <pre><code>▶ git describe --tags
  test-17-g6646502
  </code></pre>
  
  <p>Where is this thing coming from?</p>
