title: Moving a git repository up one hierarchy level
body: <p>Git beginner question:</p>
  
  <p>I have a small private webproject which is versioned locally with msysgit. There is no exterior repository, as it's only for me, so i can bascially do whatever I want.</p>
  
  <p>I've had this set up in the project directory, ie in "webroot".</p>
  
  <p>Now a second directory had to be created, placed parallel to webroot. Let's call it assets.</p>
  
  <p>So structure is now as follows:</p>
  
  <pre><code>\ project directory
  ----\webroot
  ----\assets
  </code></pre>
  
  <p>I'd love to include this new directory in the git repository, so that I'd also version changes to files stored there, but of course I can't use "git add ../assets". Neither am I inclined to create a new git project in project_directory, as this would loose all my previous commits.</p>
  
  <p>So how do I go about moving the repository out of "webroot" up into "project_directory", while keeping my commits and then being able to include "assets"?</p>
