title: How can I remove an entry in global configuration with git config?
body: <p>I ran a global configuration command in <strong>git</strong> to exclude certain files using a <code>.gitignore_global</code> file:</p>
  <pre><code>git config --global core.excludesfile ~/.gitignore_global
  </code></pre>
  <p>Is there a way to undo the creation of this setting globally?</p>
