[gnu.emacs] fixes to remote.el

raible@EW09.NAS.NASA.GOV (Eric L. Raible) (09/13/89)

Two small fixes to the recently-posted remote-editing package:

1) If you want save-some-buffers to ask about remote buffers, change
   the binding of buffer-file-name in find-remote-file to a setq:

old:
	    ;; dynamic binding for normal-mode
	    (let ((buffer-file-name (concat host file)))
	      (normal-mode)
	      ...

new:
	    (setq buffer-file-name (concat host file))
	    (normal-mode)
	    ...

2) If you have different usernames on different machines, contact me
   for a version that handles this transparently.
