This should fix fetching for people who did not use
"git svn --minimize" or cannot connect to the repository root
due to the lack of permissions.
I'm not sure what I was on when I made the change to the
rel_path() function in 4e9f6cc78e
that made it die() when we weren't connected to the repository
root :x
Thanks to Sven Verdoolaege for reporting this bug.

because the internal iterator may not have started at base.
