In my version of emacs-goodies-el there is a bug in
`twiddle-frob-mode-line-format'. When I evaluate
#+begin_src emacs-lisp
(defun twiddle-frob-mode-line-format ()
(let* ((format (default-value 'mode-line-format))
;; XEmacs 19.14 has "-%-" as the last elt by default.
(end (or (member "%-" format)
(member "-%-" format))))
(cond (end
(setcdr end (cons (car end) (cdr end)))
(setcar end 'twiddle-mode-string))
(t (nconc format '(twiddle-mode-string))))))
#+end_src
(I changed the last line) after loading the package and hit M-x
twiddle-start, at least something happens, where "something" is
different from "nothing" after all (I get a spinning bar in the
mode-line).
I guess this package is not so super useful for interactive usage.
Michael.
