title: git-svn clone with weird svn tags organization
body: <p>I want to clone a SVN tree into a git repo using git-svn. I'd like to make a complete clone, including tags and branches, but I hit a problem with the tags organization.</p>
  
  <p>the SVN tags folder looks like this:</p>
  
  <pre><code>tags/
  |-- Backup
  |   |-- 20080212
  |   `-- 20080217
  |-- V4.0.1
  |-- V4.0.2
  `-- V4.0.3
  </code></pre>
  
  <p>I know about <code>git svn clone -T trunk -b branches -t tags/Backup -t tags</code> with twice the <code>-t</code> option, but this is not entirely satisfying:</p>
  
  <pre><code>$ git branch -r
    tags/20080212
    tags/20080217
    tags/Backup
    tags/V4.0.1
    tags/V4.0.2
    tags/V4.0.3
    trunk
  </code></pre>
  
  <p>As you can see, all the tags are here, but one is too much: the <strong>Backup</strong> tag is actually not a tag but a folder containing tags. The problem is that it creates an orphan branch which duplicate the content of all the backup branches.</p>
  
  <p>The question is: How do I make git-svn ignore the backup folder but know about the backup subfolders as tags, keeping the classical tags available?</p>
  
  <p>And as a bonus: how to automatically name the Backup tags as <code>Backup/20080217</code> instead of <code>20080217</code>?</p>
  
  <p>Thanks!</p>
