title: Can I make git-svn import a Subversion repository which itself contains git repositories
body: <p>I have a project in SVN which has a plugins folder.  Several of the plugins folders are git repositories -- I added them to my plugins folder using <code>git clone</code>.</p>
  
  <p>This has been working well for me but now I'm looking to migrate my SVN repository to git using <code>git-svn</code>:</p>
  
  <pre><code>git svn init http://path/to/my/repo --no-metadata 
  git config svn.authorsfile ~/authors.txt
  git svn fetch
  </code></pre>
  
  <p>This works fine for all my early revisions which didn't have the git repos in my plugins folder, but when it hits the first revision containing a git repository it fails with the following error:</p>
  
  <pre><code>trunk/plugins/my_plugin/.git/HEAD was not found in commit 
  ae9ad0ab7cebd144c823d90d43cdab2b30d13f9e (r2259)
  </code></pre>
  
  <p>Is there a way around this to allow me to fully import my repository, perhaps by excluding any .git folders which reside in the SVN repository?</p>
