title: How to perform case insensitive diff in Git
body: <p><code>git diff</code> does not support a case-insensitive comparison of files. Google shows a very few people asking for that feature, and that too only in combination with some other <code>git diff</code> switch, like with <code>-G</code> or with <code>--color-words</code>.</p>
  
  <p>I don't care for other switches, as long as <code>git diff</code> can show me the case-insensitive diff.</p>
  
  <p>Since I didn't see any specific question towards that, and since I found a solution after an hour researching this problem, I am adding this question and the answer.</p>
