Hello again,
I think I know what the problem is, but I don't know how to fix it:
(defun jit-lock-function (start)
"Fontify current buffer starting at position START.
This function is added to `fontification-functions' when `jit-lock-mode'
is active."
(when (and jit-lock-mode (not memory-full))
(if (null jit-lock-defer-timer)
;; No deferral.
(jit-lock-fontify-now start (+ start jit-lock-chunk-size))
;; Record the buffer for later fontification.
(unless (memq (current-buffer) jit-lock-defer-buffers)
(push (current-buffer) jit-lock-defer-buffers))
;; Mark the area as defer-fontified so that the redisplay engine
;; is happy and so that the idle timer can find the places to fontify.
(with-buffer-prepared-for-jit-lock
(put-text-property start
(next-single-property-change
start 'fontified nil
(min (point-max) (+ start jit-lock-chunk-size)))
'fontified 'defer)))))
There are 3 s-expressions inside (if ...), the third will never run,
but it probably has to. Maybe it should be (when ...) instead of (if
...)?
Best.
Oleg
