title: git status didn't show modified files
body: <p>I created a branch, say 'new_branch' from the develop branch on bitbucket and from my local I switch to it </p>
  
  <pre><code>git checkout -b new_branch 
  </code></pre>
  
  <p>After I git pull the code, I tried </p>
  
  <pre><code>git status 
  </code></pre>
  
  <p>to see the modified files. </p>
  
  <p>However from the output, I didn't see one file that I knew was modified, other modified files seemed OK.</p>
  
  <p>For that particular file, say 'test.cs', I did</p>
  
  <pre><code>git diff origin/new_branch -- local-path/test.cs
  </code></pre>
  
  <p>and confirm the change, but how come wasn't it shown on the 'git status' output?</p>
  
  <p>As a result I can't do add/commit/push the file in.</p>
  
  <p>Can anyone help? Hope I made myself clear.</p>
