I didn't think through this check, which would have been obvious had I
ran the added test without the rest of the patches in this series.  It
assumes that the 'git add --dry-run' call fails, but that failure
depends on the last patch of this series.  So I'd need to move this
patch to the end or find a new place for this "no commits" check.
