Additionally, this sets `masterRepoURL` to "/private/var/ *bunchofdirectories* /repositories" instead of what I expected (" *stuff* /repositories/whatever"). Is this normal ?

In any case, the following call to `-cloneFromURL:` fails with an underlying error of "could not find repository from /private/var/ *bunchofdirectories* /repositories/", which I'm diagnosing as `fileURL` being wrong, but my mind dwindles at that thought ;-).

The rest of the test I've written asserts like crazy because of that failed `-clone...`.
