title: Un-ignore all files in global .gitignore
body: <p>After looking at <a href="https://stackoverflow.com/questions/3203228/git-ignore-exception">git ignore exception</a>, I realized that one can ignore files in a repository from a global .gitignore file.</p>
  
  <p>Is there any way that you can override all rules from the global .gitignore file, so that the repository will have everything in it and nothing ignored? (besides un-ignoring every file individually)</p>
