title: Import previous commits using git-svn
body: <p>What I have done so far:</p>
  
  <pre><code>git svn init http://example.com/svn/trunk
  </code></pre>
  
  <p>(latest revision is 1000)</p>
  
  <pre><code>git svn fetch -r1000
  git svn rebase
  </code></pre>
  
  <p>My repo is up to date and I have in the logs all commits since rev. 1000.</p>
  
  <p>How to import the history since revision 800?<br>
  How to checkout to the revision 800?</p>
