title: How to rename upstream trunk in git-svn?
body: <p>I have a local it repository that was fetched from upstream git-svn repository with git-svn. At some moment, upstream repository's trunk (it has nonstandard layout) was renamed there.</p>
  
  <p>From that moment i can no longer dcommit or fetch new commits. If i try and change (manually) svn-remote.remotename.url, i get error "Unable to determine upstream SVN information from working tree history", which kind of makes sense but helps me none.</p>
  
  <p>Is there a way to solve the issue that doe not involve fetching again?</p>
  
  <p>I have tried setting rewriteRoot property (to new url), also without any discernible result.</p>
