title: Warning on "diff.renamelimit variable" when doing git push
body: <p>I'm pushing the local commit to the remote git server and got the following warning messages:</p>
  
  <pre><code>remote: warning: only found copies from modified paths due to too many files.
  remote: warning: you may want to set your diff.renamelimit variable to at least 19824 and retry the command.
  </code></pre>
  
  <p>But actually I've already set the diff.renamelimit to 0 (I think zero means unlimited, right?).</p>
  
  <pre><code>$ git config --list
  ...
  diff.renamelimit=0
  </code></pre>
  
  <p>So what shall I do to avoid this warning? Thanks.</p>
