Close Gitlab issue via commit : <p>I spend my day doing this:</p>

<ol>
<li>Read an issue on a Gitlab-powered issue tracker,</li>
<li>Fix the issue,</li>
<li>Commit and push to the same Gitlab-powered Git server,</li>
<li>Mark the issue as closed.</li>
</ol>

<p>To remove the 4th step, how can I close the issue automatically when committing?</p>
