;;; Patch file for System version 123.52
;;; Reason:
;;;  Unfortunately, FTP-ACCESS as written uses the :directory-list method for both
;;;  Dired and :multiple-file-plists (called by make-system).  These want contrary
;;;  formats for the directory list: Dired wants the truename as the car, make-system
;;;  wants the pathname it specified.  Solution: :directory-list always sets up the
;;;  truename (and thus Dired's of all flavors work well), and we provide a
;;;  :multiple-file-plists method that doesn't call :directory-list, but
;;;  does the right thing itself.
