title: Working with submodules within submodules
body: <p>I am experiencing some troubles managing some repositories on Github.
  I am actiually mainting a pathfinding library. The master repo is here: <a href="https://github.com/Yonaba/Jumper" rel="nofollow noreferrer">Jumper</a>.This repo connected to 2 others, included as submodules (<a href="https://github.com/Yonaba/30log" rel="nofollow noreferrer">30log</a> and <a href="https://github.com/Yonaba/Binary-Heaps" rel="nofollow noreferrer">Binary-Heaps</a>).</p>
  
  <p>When I attempt to clone the master repo (Jumper), using <em>--recursive</em> as an option, <strong>it works fine.</strong></p>
  
  <p>But, when I want to include this master repo as a submodule in another one, let's call it <strong>SuperMaster repo</strong>, and then I attempt to <em>clone SuperMaster repo</em>, still using <em>--recursive</em>, it succeeds to clone the repo <em>Jumper</em>, but fails to register its submodules (<em>30log</em> and <em>Binary-Heaps</em>), saying something like:</p>
  
  <pre><code>Failed to recurse into submodule path 
  fatal: not a git repository: ../../../../c:/Users/... etc
  </code></pre>
  
  <p>I dug a bit, and I found some people have encountered something similar (<a href="https://stackoverflow.com/questions/10327628/why-does-recursive-submodule-update-from-github-fail-for-doctrinemongoormmodule">here</a> and <a href="http://git.661346.n2.nabble.com/git-submodule-path-computation-bug-with-recursive-submodules-td7562568.html" rel="nofollow noreferrer">here</a>) but noone of the solutions proposed seems to work with me.</p>
