Todays question:
Can You when You execute this
(message "YY:before: font-lock-keywords-only =%s in buffer %s,
def=%s" font-lock-keywords-only (current-buffer) (default-value
font-lock-keywords-only))
(if (nth 1 defaults)
(set (make-local-variable 'font-lock-keywords-only) t)
(kill-local-variable 'font-lock-keywords-only))
(message "YY:after : font-lock-keywords-only =%s in buffer %s,
def=%s" font-lock-keywords-only (current-buffer) (default-value
font-lock-keywords-only))
and gett this output? :
YY:before: font-lock-keywords-only =nil in buffer only-html.html, def=nil
YY:after : font-lock-keywords-only =t in buffer only-html.html, def=t
I can. Unfortunately.
However I can only do this magic with MuMaMo. But I do not understand
how it does it. Anyone?
Hint: This is in a call from fontification-functions. And the function
where I added the trace above is font-lock-set-defaults.
I am taking a pause now. Some fresh air.

Ah, did not notice, but in this case the output will be the same
(since font-lock-keywords-only is either t or nil).

That's not true in general:
(set 'foo t (make-local-variable 'foo) nil)
(cons (default-value foo) (default-value 'foo))

Nice example (but set takes only two pars), but I have of course
tested the output again to see if everything is as I thought.
Please see the bug report for more information.
