Start tracking branches/tags on a git-svn repo that was tracking only trunk

Question

I've started tracking an svn repository with git by cloning only its trunk directory. Now I want to track the other stuff, but I don't want to have to clone it again just to use --stdlayout since it takes a long time to download and I already have most of the code locally. How do I change the repository layout to match svn trunk/branches/tags scheme without having to clone again?

Old .git/config:

[svn-remote "svn"]
        url = svn://host/project/trunk
        fetch = :refs/remotes/git-svn

New .git/config:

[svn-remote "svn"]
        url = svn://host/project
        fetch = trunk:refs/remotes/git-svn
        branches = branches/*:refs/remotes/*
        tags = tags/*:refs/remotes/tags/*

Now run git svn reset -r1 -p; git svn fetch; git svn rebase.

No, it's not much different from doing a git svn clone anew -- adding branches means that git can see more merges which means the content git is tracking has changed so git-svn must regenerate everything.
