After git svn clone master is tied to a branch in svn, howto set master to trunk

Hi, after performing a $> git svn clone https://svnserver/svn/a/b/c -T trunk/current -t tags - b branches I find that the git master has been tied to one of the branches. It turns out that the highest svn revision number in the repository was tied to that branch.

For historical reasons we have subdirectories in trunk/ on svn, but I
inspected .git/config
[svn-remote "svn"]
        url = https://svnserver/svn
        fetch = a/b/c/trunk/current:refs/remotes/trunk
        branches = a/b/c/branches/*:refs/remotes/*
        tags = a/b/c/tags/*:refs/remotes/tags/*
And I assume it picked up the strange trunk correctly.

I have been googling around for a while looking for instructions how to tell git that when I check out "master" it should be "trunk" from svn and not "branches/next_gen", or more precisely how to move master to trunk from branches/next_gen.

I guess I could solve the problem by modifying a file in trunk on svn and commit so that the trunk will get the highest svn revision number again and redo the clone.
