    Fix building of VC package manuals with relative org links/includes
    
    * lisp/emacs-lisp/package-vc.el (package-vc--build-documentation):
    Ensure that default-default is the docs-directory around
    org-export-to-file to ensure that links to relative files work
    correctly.  (Bug#65243)
