title: Gerrit Error: commit subject >65 characters; use shorter first paragraph
body: <p>We started to use the Gerrit code review recently. Sometimes when you make a simple commit and try to make a push to Gerrit, this error is displayed:</p>
  
  <pre><code>   remote rejected
     commit subject &gt;65 characters; use shorter first paragraph
  </code></pre>
  
  <p>I looked in the web but did not find how to solve this problem. I tried to make an amend in the previous commit and reduce the size of the commit message, but the error remains.</p>
  
  <p>What kind of error is that? And how to solve it? Is there some Gerrit configuration about the size of the commit message?</p>
