title: What is the difference between git describe --abbrev=0 and git describe --abrev=0 --tags
body: <p>I have a repo with the following output:</p>
  
  <blockquote>
  <pre><code>$ git tag
  product-picker-v1
  v0.0.1
  v0.0.2
  v0.0.3
  v0.0.4
  v0.1
  v0.1.1
  v0.1.10
  v0.1.11
  v0.1.12
  v0.1.12.1
  v0.1.13
  v0.1.14
  v0.1.15
  v0.1.2
  v0.1.3
  v0.1.4
  v0.1.5
  v0.1.6
  v0.1.7
  v0.1.8
  v0.1.9
  </code></pre>
  </blockquote>
  
  <pre><code>$ git describe --abbrev=0
  v0.1.14
  
  $ git describe --abbrev=0 --tags
  v0.1.15
  </code></pre>
  
  <p>Why do I get one tag back when I run git describe without the <code>--tags</code> option?</p>
