[GIT-SVN] master follows not trunk

Hi,

it seams so, that git-svn sets the master branch to that svn branch
which has the highest revision!

I cloned a svn repo today where exactly this happend. I.e. master
pointed not to the trunk but to the branch with the highest revision.
After trunk moved forward, a git svn rebase told me that master is up
to date.

A second clean clone of this repo and master pointed to trunk.

Is this indented?
