Since unhandled.log stores paths relative to the repository
root, we need to strip out leading path components if the
directories we're tracking are not the repository root.

We parse unhandled.log files for empty_dir statements and make a
best effort attempt to recreate empty directories on fresh
clones and rebase. This should cover the majority of cases
where users work off a single branch or for projects where
branches do not differ in empty directories.
Since this cannot affect "normal" git commands like "checkout"
or "reset", so users switching between branches in a single
working directory should use the new "git svn mkdirs" command
after switching branches.
