title: Git fetch a branch once with a normal name, and once with capital letter
body: <p>I'm fetching for remote branches and stuck in some sort of a loop.</p>
  
  <p>I fetch once and get:</p>
  
  <pre><code>$ git fetch
  * [new branch]      minorRelease/something-&gt; origin/minorRelease/something
  </code></pre>
  
  <p>And then I fetch again and get:</p>
  
  <pre><code>$ git fetch
  * [new branch]      minorRelease/Something-&gt; origin/minorRelease/Something
  </code></pre>
  
  <p>Same branch but with a capital <code>S</code>.</p>
  
  <p>I tried to delete the file from the following folder <code>.git/refs/remotes/origin/minorRelease</code>, but when fetching again, I get both and return to the loop above:</p>
  
  <pre><code>$ git fetch
  * [new branch]      minorRelease/Something-&gt; origin/minorRelease/Something
  * [new branch]      minorRelease/something-&gt; origin/minorRelease/something
  </code></pre>
