Sometimes users are given only read access to a subtree inside a
repository, and git-svn could not read log information (and thus
fetch commits) when connecting a session to the root of the
repository. We now start an SVN::Ra session with the full URL
of what we're tracking, and not the repository root as before.
This change was made much easier with a cleanup of
repo_path_split() usage as well as improving the accounting of
authentication batons.
