Gnus no longer highlights articles in CVS version

Gnus no longer highlights articles in CVS version

[Klaus Zeitler]

In emacs 21 and 22 I have Gnus display its articles in a gaudy way.
For some odd reason this doesn't work anymore in the CVS version.
I tracked this down to some real old code in my .emacs file, that I
use to display tabs with a slightly different background.

(defun show-tabs () "Show tabs with a slightly changed background"
  (font-lock-add-keywords nil '(("[\t]"  (0 'tab-face t)))))
(add-hook 'font-lock-mode-hook 'show-tabs)

This will add '("\t" (0 'tab-face t))' to each buffers font-lock-keywords.
I have no idea why it breaks syntax highlighting in Gnus.
(BTW I haven't used the CVS version since emacs 22 came out).

I'd give my right arm to be ambidextrous.

It activates font lock's fontification mechanism, which removes the
`face' properties that Gnus added "manually".
