Untracked file paths not indented like unstaged and staged

[akappen]

Untracked file paths do not include the mode class on the empty span:

<div class="file" mousedown="clicked" is="space-pen-div">
  <span></span>
  <span class="path">.ruby-gemset</span>
</div>

Staged and unstaged do, which adds left padding:

<div class="file" mousedown="clicked" is="space-pen-div">
  <span class="mode">M</span>
  <span class="path">config/initializers/rails_admin.rb</span>
</div>
