Re: ftp oddities

I see.  The problem is that emacs-w3m uses ange-ftp even if
w3m-use-ange-ftp is nil.  What ever on earth has happened?!

Try the following and let us know the result, that is, the Lisp
backtrace. (Copy it into the *scratch* buffer and type `C-j' at
the end of the last line.)

(progn
  (setq debug-on-error t)
  (load "w3m.el")
  (fset 'w3m-goto-ftp-url (lambda (&rest args)
			    (error "!! `w3m-goto-ftp-url' is called")))
  (unwind-protect
      (w3m-goto-url "ftp://ftp.gwdg.de/";)
    (load "w3m")))

If the "!! `w3m-goto-ftp-url' is called" message doesn't appear
in the beginning of the *Backtrace* buffer, there might be
another cause.
