title: git commit -m not working
body: <p>I have been committing to my local repository today with <code>git commit -a</code> and entering my commit messages. Everything fine.</p>
  
  <p>At the end of the day I wanted to commit a small change with a single line commit, so I used <code>git commit -m "some message"</code> and got the following:</p>
  
  <pre><code>On branch ChartFeature
  Your branch is ahead of 'origin/ChartFeature' by 2 commits.
    (use "git push" to publish your local commits)
  Changes not staged for commit:
          modified:   SomeFolder/Scripts/app/SomeScript.js
  
  no changes added to commit
  </code></pre>
  
  <p>What have I done wrong? </p>
  
  <p>How do I get git to allow <code>commit -m</code> again?</p>
  
  <p>Footnote: After failing with <code>-m</code> a few times and seeing nothing wrong with <code>git log origin/ChartFeature..HEAD</code> I tried <code>git commit -a</code> as before and it worked (as expected) though <code>git commit -m</code> still does not.</p>
