If you `describe-function' on a generic method, the resulting *Help*
buffer shows the various implementations correctly. However,
clicking/RET on the implementation links fails with:
Debugger entered--Lisp error: (wrong-number-of-arguments (lambda (fun file)
(require (quote find-func)) (if (eq file (quote C-source)) (progn (setq file
(help-C-file-name (indirect-function fun) (quote fun))))) (let ((location
(find-function-search-for-symbol fun nil file)))
(my-find-symbol-switch-to-buffer (car location)) (if (cdr location) (goto-char
(cdr location)) (message "Unable to find location in file")))) 3)
help-do-xref(nil (lambda (fun file) (require (quote find-func)) (if (eq file
(quote C-source)) (progn (setq file (help-C-file-name (indirect-function fun)
(quote fun))))) (let ((location (find-function-search-for-symbol fun nil
file))) (my-find-symbol-switch-to-buffer (car location)) (if (cdr location)
(goto-char (cdr location)) (message "Unable to find location in file"))))
((bbdb-db-load bbdb-db) "/home/eric/.emacs.d/bbdb/lisp/bbdb.el" cl-defmethod))
help-button-action(#<marker (moves after insertion) at 276 in *Help*>)
button-activate(#<marker (moves after insertion) at 276 in *Help*> nil)
push-button(276)
funcall-interactively(push-button 276)
call-interactively(push-button nil nil)
command-execute(push-button)
Basically, when `help-button-action' does this:
(help-do-xref nil
(button-get button 'help-function)
(button-get button 'help-args))
There are three 'help-args (the first arg is the specializer --
actually, maybe there as many args as there are specializers? don't
know), but the 'help-function only takes two args.
Hope that's enough to get it there!
