-;; Attention!
-;; It would be nice if ange-ftp-add-hook was generalized to
-;; (defun ange-ftp-add-hook (hook-var hook-function &optional postpend),
-;; where the optional postpend variable stipulates that hook-function
-;; should be post-pended to the hook-var, rather than prepended.
-;; Then, maybe we should overwrite dired with
-;; (ange-ftp-add-hook 'dired-load-hook 'ange-ftp-overwrite-dired t).
-;; This is because dired-load-hook is commonly used to add the dired extras
-;; features (dired-x.el, dired-trns.el, dired-nstd.el, ...). Some of these
-;; extras features overwrite functions in dired.el with fancier versions.
-;; The "extras" overwrites would then clobber the ange-ftp overwrites.
-;; As long as the ange-ftp overwrites are carefully written to use
-;; ange-ftp-real-... when the directory is local, then doing the ange-ftp
-;; overwrites after the extras overwites should be OK.
-;; At the moment, I think that there aren't any conflicts between the extras
-;; overwrites, and the ange-ftp overwrites. This may not last though.
