git svn --version requires working copy

Hi

I've just noticed, that running git svn --version requires working copy,
what is quite ugly to require working copy just to figure out if git svn
is installed and what version.

$ git svn --version
fatal: Not a git repository (or any parent up to mount point /home)
Stopping at filesystem boundary (GIT_DISCOVERY_ACROSS_FILESYSTEM not set).
Unable to find .git directory
 at /usr/lib/git-core/git-svn line 347.

Is this expected behavior?

Thanks
