I have a git repository linked to a svn repository with git-svn, including a branch path configuration and an authorsfile for svn username -> email mapping. When running `git svn branch new_branch`, git-svn: * Creates a svn commit creating a new svn branch * Creates a local git commit linked to this svn commit The svn commit is correctly generated, but the corresponding git commit has a bad author: the author is just the svn username. Re-fetching the svn repository then properly applies the authors file, but ideally it would do it directly when creating the branch.
