title: unexpected changes after checkout
body: <p>I have a remote GIT repository, which I clone locally. </p>
  
  <p>After that I change the branch to another one, do nothing, then try to change to another branch, and GIT is saying there are uncommitted changes!?! </p>
  
  <p>How in the world there are changes if I didn't do anything just changed branches.</p>
  
  <p>See this action in the console.</p>

  <p>I did set </p>
  
  <p><code>git config --system core.autocrlf false</code></p>
  
  <p>but it didn't help. </p>
  
  <p>What's happening here, never saw such a behavior. The guy who committed to <code>perftech</code> branch works under Windows as me.</p>
  
  <p>thx</p>
