title: Git tab completion not working in zsh on mac
body: <p>No matter what I try and do I can't seem to make git tab/auto completion work in my zsh shell. I've downloaded the bash-completion script and the zsh-completion one and followed the instructions, but I can't make it work. </p>
  
  <p>I've reinstalled oh-my-zsh but that didn't seem to help or make any difference. </p>
  
  <p>Can anyone who's got it working describe to me their setup so I can try an emulate it to get it working for me?</p>
  
  <p>To be specific, what I've done so far is:</p>
  
  <ul>
  <li>Switched to using zsh as my default shell</li>
  <li>Installed oh-my-zsh</li>
  <li>Downloaded <a href="https://github.com/git/git/blob/master/contrib/completion/git-completion.bash">https://github.com/git/git/blob/master/contrib/completion/git-completion.bash</a> and saved it in <code>~/.completion/git/git-completion.sh</code></li>
  <li>Downloaded <a href="https://github.com/git/git/blob/master/contrib/completion/git-completion.zsh">https://github.com/git/git/blob/master/contrib/completion/git-completion.zsh</a> and saved that in <code>~/.zsh/_git</code></li>
  <li>Added <code>zstyle ':completion:*:*:git:*' script ~/.completion/git/git-completion.sh</code></li>
  </ul>
  
  <p>No luck.</p>
