title: SVN: Create a diff for lots of revisions
body: <p>I had a private branch that I did a ton of commits to, then I merged it into trunk, and did a few little tweaks there.</p>
  <p>Now the trunk maintainer wants a diff off all of my changes incase we need a rollback.</p>
  <p>How can I create this? If you need numbers for your examples, assume that</p>
  <p><code>224446</code></p>
  <p>was my main revision where I merged into trunk,</p>
  <p><code>224453</code> and <code>224462</code></p>
  <p>were my minor fixes, and I have countless changes when in my private branch.</p>
