I\'m using emacs 24 on OS X and have the strange problem that I\'m unable to see any color codes. Emacs seems to just ignore them. My motivation is to see colored output from cm
I can definitely say it's working fine for me with just (ansi-color-for-comint-mode-on). FWIW you can browse my emacs config, but it's fairly big :)
