title: Idea Intellij - compare between branches - contents are identical
body: <p>I have a strange behavior in IDEA.
  While I'm comparing two different branches (one downloaded to local and one in repo), I get list of files with "differences".</p>
  
  <p>The thing is, when I double click the file, it shows that files are identical and message <code>Contents are identical</code></p>
  
  <p>Is that really so? Is something cached in Idea? Or is it some bad behavior of <code>SVN</code>?</p>
