Here is some Elisp that indicates something should be
improved...

(defun buffer-menu-custom-font-lock ()
  (interactive)
  (let ((font-lock-unfontify-region-function
         (lambda (start end)
           (remove-text-properties start end '(font-lock-face nil)))))
    (font-lock-unfontify-buffer)
    (set (make-local-variable 'font-lock-defaults)
         '(buffer-menu-buffer-font-lock-keywords t))
    (font-lock-ensure) ))

(But... I don't think I wrote that. It looks like
something from the wiki, perhaps.)
