title: How do I get the original revision for a branch in SVN?
body: <p>According to <a href="http://grep.codeconsult.ch/2008/11/26/what-svn-revision-was-this-branch-created-in/" rel="nofollow">this blog post</a> This command should tell me when the <code>release-2.0.2rc1</code> tag of protobuf was created:</p>
  
  <blockquote>
    <p>svn log -v -r0:HEAD -l1 --stop-on-copy <a href="http://protobuf.googlecode.com/svn/tags/release-2.0.2rc1/" rel="nofollow">http://protobuf.googlecode.com/svn/tags/release-2.0.2rc1/</a></p>
  </blockquote>
  
  <p>However it does not:</p>
  
  <pre><code>svn log -v -r0:HEAD -l1 --stop-on-copy http://protobuf.googlecode.com/svn/tags/release-2.0.2rc1/
  ------------------------------------------------------------------------
  r54 | kenton@google.com | 2008-09-29 20:26:43 -0400 (Mon, 29 Sep 2008) | 3 lines
  Changed paths:
     M /tags/release-2.0.2rc1/configure.ac
     M /tags/release-2.0.2rc1/java/pom.xml
     M /tags/release-2.0.2rc1/python/setup.py
  
  Update version number in 2.0.2rc1 release branch.
  </code></pre>
  
  <p>If I look at revision 53, I get the actual copy:</p>
  
  <pre><code>svn log -v -r53 -l1 --stop-on-copy http://protobuf.googlecode.com/svn/
  ------------------------------------------------------------------------
  r53 | kenton@google.com | 2008-09-29 20:23:29 -0400 (Mon, 29 Sep 2008) | 3 lines
  Changed paths:
     A /tags/release-2.0.2rc1 (from /trunk:52)
  
  Tagged release candidate 2.0.2rc1.
  </code></pre>
  
  <p>So that command seems to get me the revision after the copy. How do I get the command that gives me the revision the branch was made?</p>
