Notes:
    The output of the differential testing is below,
    which points out 2 bugs:
    * resolving relative paths seems is broken, so we
      would need to have the equivalent of
        eval "set $(git rev-parse --sq --prefix "$wt_prefix" -- "$@")"
      (091a6eb0, 2013-06-16,  submodule: drop the top-level requirement)
    * The handling of funny characters is broken.
