title: git svn importing a branch with a trailing space
body: <p>I'm importing a svn repository into git using <code>git svn</code>. I'm using Git-1.8.0-preview20121022 on Windows Server 2008 R2.</p>
  
  <p>The import's been running for a while and has fetched the first 4000 revisions without incident. However, it now seems to have come across a branch name with a trailing space and it has fallen over.</p>
  
  <pre><code>$ git svn fetch
  Found possible branch point: https://10.10.10.2/svn/project/trunk =&gt; https://10.10.10.2/svn/project/branches/Release%2020110929%20, 3976
  Found branch parent: (refs/remotes/Release 20110929 ) 691fb7f7d11cbb1afe35106f60a1d117ba415f4c
  fatal: Unable to create 'd:/GitMigration/project/.git/svn/refs/remotes/Release 20110929 /index.lock': No such file or directory
  read-tree 691fb7f7d11cbb1afe35106f60a1d117ba415f4c: command returned error: 128
  </code></pre>
  
  <p>This branch doesn't exist any more so I can't change the name in the normal way. The directory exists without the trailing space in the name but I can't find a way to rename it that preserves the space.</p>
  
  <p>Is there anything I can do about this?</p>
