title: svn diff: Compare my local uncommited changes with an arbitrary version of the file from the repository
body: <p>Let's say I've checked out revision 10 of hello.c which is the latest one in the repository. I've made some changes to hello.c locally in my workspace, but I haven't committed it yet. Now, how can I compare this local uncommitted changes made on top of revision 10 with, say, revision 7 of hello.c in the repository?</p>
  
  <p>Thanks for your time!</p>
