With the following in my .emacs I get narrow margins in text-mode buffers:
(defun my-set-margins ()
"Set margins in current buffer."
(setq left-margin-width 30)
(setq right-margin-width 30))
(add-hook 'text-mode-hook 'my-set-margins)
How can I change the color of the lines that appear to delimit these margins so that it's the same as my background color and not black like they are now?
EDIT
I know more now and this is my question:
How do I add a hook to turn of the fringes in text-mode?
