How to set line number to start at 0?
If you want line number to start at 0, put this in your emacs init file:
(require 'linum) (setq linum-format (lambda (line) (propertize (number-to-string (1- line)) 'face 'linum)))
Setting line number to start at 0 is useful because some editors do that. See: bug#4274.
