Some utilities for more tight git-svn integration.
git-svn-fetchbranch <remote branch name>
Fetches the remote branch from svn, and creates a local git branch which tracks it.
git-svn-lsbranches
Simple command which lists all remote svn branches.
Assuming your install lives in ~/src/git-svn/utils, add these to your .bashrc:
export PATH=$HOME/srv/git-svn-utils/bin:$PATH
And to setup bash completion for branch names from svn:
source $HOME/src/git-svn-utils/bash_completion
