Hi,

I recently tried to disable jit-lock-mode using the usual syntax
(jit-lock-mode -1)

However, the mode was not disabled, which is unexpected.
I believe that the problem is caused by

....
If you need to debug code run from jit-lock, see `jit-lock-debug-mode'."
  (setq jit-lock-mode arg) ;; <- this sets jit-lock-mode to non-nil even if I pass -1 argument
  (cond
   ((and (buffer-base-buffer)
....

Best,
Ihor
