title: How to display SVN copy/rename operations in svn diff?
body: <p>When I'm trying to show revision changes with <code>svn diff --summarize</code>
  only deleting+adding showed instead of rename
  and adding (without source) when its copy operation.</p>
  
  <p>Of course, copy &amp; rename was applied with svn commands
  and I can see that there is copy in TortoiseSVN, 
  but not from command line... How I can do this?</p>
