title: Git global ignore not working
body: <p>I've created the file <code>.gitignore_global</code> and put it in my git install directory. When I run the command:</p>
  
  <pre><code>git config --global core.excludesfile ~/.gitignore
  </code></pre>
  
  <p>the rules in the ignore file do not get applied to my commits.</p>
  
  <p>When I rename the file <code>.gitignore</code> and put it in my project root, the rules do apply.</p>
  
  <p>What is wrong here?</p>
