Git-SVN with multiple branch locations?

You can add multiple branches and tags entries in your git-svn config, even retroactively. So if normally SVN branches live in branches/* in your SVN repo (ie. a standard layout), but you also have branches/summer-students/*, you can set it up in .git/config like below:

[svn-remote "svn"]
    url = svn+ssh://svn.example.com
    fetch = trunk:refs/remotes/trunk
    branches = branches/*:refs/remotes/*
    tags = tags/*:refs/remotes/tags/*

    branches = branches/summer-students/*:refs/remotes/svn-summer-students/*

On the left of the : is the path in the SVN Repo, and on the right is the path it will appear as in your git remote branch list. You can use refs/remotes/* repeatedly to have everything appear as a top-level remote branch, but watch out for name collisions - they will break things (hence svn-summer-students instead of summer-students, which already exists).

After you edit the config, you need to delete .git/svn/.metadata and run git svn fetch to refresh the branch list and regenerate it. git branch -r should then show the extra branches. If you get errors, look out for naming collisions.

The git svn docs have some more examples of specifying paths via wildcards or expressions if you have a funky SVN layout.

For those looking to do this retroactively, the git-svn manpage for 1.7.x says:

It is also possible to fetch a subset of branches or tags by using a comma-separated list of names within braces. For example:

[svn-remote "huge-project"]
     url = http://server.org/svn
     fetch = trunk/src:refs/remotes/trunk
     branches = branches/{red,green}/src:refs/remotes/branches/*
     tags = tags/{1.0,2.0}/src:refs/remotes/tags/*
