Ok, how do we go about deciding where the bug(s) lies? Clearly,
linum is meant to work in all buffers:
linum.el:26:
;; Display line numbers for the current buffer.
;;
;; Toggle display of line numbers with M-x linum-mode. To enable
;; line numbering in all buffers, use M-x global-linum-mode.
This is the behavior I need -- I use voice commands to navigate among
lines and designate ranges of lines for operations -- so simply changing
linum's spec so that it does not work in fundamental buffers is
unacceptable.
Should linum use a different implementation method than
define-globalized-minor-mode? (does one exist?)
Should we instead fix define-globalized-minor-mode to work with all
buffers? Its documentation via ^h f claims it works in every buffer:
define-globalized-minor-mode is an autoloaded Lisp macro in
`easy-mmode.el'.
(define-globalized-minor-mode global-mode mode turn-on &rest keys)
Make a global mode global-mode corresponding to buffer-local minor mode.
turn-on is a function that will be called with no args in every buffer
and that should try to turn mode on if applicable for that buffer.
Clearly at a minimum this is inconsistent with
define-globalized-minor-mode's actual behavior and Elisp manual entry.
What do people think?
