Re: a emacs mode to see newline, tabs, spaces

Hi Drew,

When highlighting tab characters with the following snippet of code, my Gnus
Group buffer becomes black-and-white only.

--8<---------------cut here---------------start------------->8---
;; highlight tabs
(require 'show-wspace)
(add-hook 'font-lock-mode-hook 'highlight-tabs)
--8<---------------cut here---------------end--------------->8---

Same happens with the following:

--8<---------------cut here---------------start------------->8---
;; highlight tabs in all modes
(add-hook 'font-lock-mode-hook
          '(lambda ()
             (font-lock-add-keywords
              nil
              '(("\t" 0 'trailing-whitespace prepend)))))
--8<---------------cut here---------------end--------------->8---

Any idea why?

Best regards,
  Seb
