title: Git status and git diff show no changes
body: <p>I made changes to my code and typed:</p>
  
  <p><code>git status</code></p>
  
  <p>Which returned</p>
  
  <p><code>Your branch is up-to-date with 'origin/branch_name'.
  nothing to commit, working directory clean</code></p>
  
  <p>Then I typed</p>
  
  <p><code>git diff</code></p>
  
  <p>Which didn't print out anything...</p>
  
  <p>Can someone help? It should be showing me files that were changed...</p>
  
  <p>Thanks in advance!</p>
