For the case of multiple projects sharing a single SVN repository, it is
common practice to create the standard SVN directory layout within a
subdirectory for each project. In such setups, access control is often
used to limit what projects a given user may access. git-svn failed to
detect branches (e.g. when passing --stdlayout to clone) because it
relied on having access to the root directory in the repository. This
patch solves this problem by making git-svn use paths relative to the
given repository URL instead of the repository root.

I've already posted this on May 31st but received no feedback, so here
is the patch again against current git.git. I'm using this at work to be
able to checkout a complete SVN project including all branches and tags
in one go without having to create an individual remote for each branch
and tag. Any chance we can get this into mainline git?
Cheers,
Mattias
