git-svn: fix fetching new directories copies when using SVN:: libs

Log output from SVN doesn't list all the new files that were
added if a new directory was copied from an existing place in
the repository.  This means we'll have to do some extra work and
traverse new directories ourselves.

This has been updated from the original patch to defer traversed
adds until all removals have been done.  Please disregard the
original.

Thanks to Ben Williamson for the excellent bug report and
testing.
