title: Exit Vim without committing changes in Git
body: <p>When I use <code>git commit --amend</code> or <code>git rebase -i</code>, vim opens up for me to make changes. If I then change my mind and exit vim without making any changes, a commit is still made which shows up in <code>git reflog</code>.</p>
  
  <p>How do I exit the editor without committing anything?</p>
