title: Message 'src refspec master does not match any' when pushing commits in Git
body: <p>I clone my repository with:</p>
  
  <pre><code>git clone ssh://xxxxx/xx.git 
  </code></pre>
  
  <p>But after I change some files and <code>add</code> and <code>commit</code> them, I want to push them to the server:</p>
  
  <pre><code>git add xxx.php
  git commit -m "TEST"
  git push origin master
  </code></pre>
  
  <p>But the error I get back is:</p>
  
  <pre class="lang-none prettyprint-override"><code>error: src refspec master does not match any.  
  error: failed to push some refs to 'ssh://xxxxx.com/project.git'
  </code></pre>
