title: Git submodule is returning blank?
body: <p>I'm trying to use <code>git submodule update</code> and it's not returning anything, nor does any of the <code>git submodule</code> commands, and I have checked the <code>.gitmodules</code> file and it is correct?</p>
  
  <p>I have no idea if git can be debugged or what, and it's really annoying.</p>
  
  <p>There's no errors or anything, even when using <code>2&gt;&amp;1</code> on  the end which is really worrying.</p>
