title: Restore SVN ancestry of file copied and then edited
body: <p>I have a file in SVN that I copied a while back. The only problem is that I didn't do it with an <code>svn cp</code>, I did with with a normal <code>cp</code>. Now, I've made a bunch of edits to the file but it doesn't have any ancestry; the logs report it being added wholesale instead of being copied.</p>
  
  <p>Is there a way for me to fix my SVN repository such that it contains both information about the copy and my edits?</p>
