The Dude Abides


While crafting another patch for cc-mode, I stumbled upon the following:

;; RMS says don't make these the default.
;; (April 2006): RMS has now approved these commands as defaults.
(unless (memq 'argumentative-bod-function c-emacs-features)
  (define-key c-mode-base-map "\e\C-a"    'c-beginning-of-defun)
  (define-key c-mode-base-map "\e\C-e"    'c-end-of-defun))

I’ve seen this kind of thing before, but it keeps puzzling me. Why would you:

  • Put a comment there about not making the following a default
  • Put a clarifying comment how these have been approved as defaults now
  • Keep both comments to trip up future readers

Any other project I’m involved in would immediately remove that commentary. Emacs is the only one where suggesting such drastic action would yield a lengthy bikeshedding discussion about the merits of pre-VCS traditions and how keeping them will toughen up whoever may join in the collaborative development effort. Yes, seriously.
