But it should be covered by global-font-lock-mode by default.
I see that font-lock-mode is indeed enabled but `font-lock-specified-p'
fails for a text-mode buffer, so you get a buffer with font-lock-mode on
but no fontification. Maybe using font-lock-add-keywords without
setting any other font-lock variables confuses font-lock? An explicit
`font-lock-set-defaults' call helps btw.
Michael.
