Your code does something you definitely shouldn't do: your advices make
`hi-lock-set-file-patterns' and `hi-lock-find-patterns' switch to a
different buffer (persistently!). When you need the context of another
buffer, use `with-current-buffer' to switch to it temporarily.
Maybe the following illustration may help:
(defvar-local foo)
Suppose we have two buffers buffer-a and buffer-b. buffer-a is current,
and we want to set `foo's binding in buffer-a to `foo's value in
buffer-b (I think this is what you try to do, more or less). This is
how you can do it
--8<---------------cut here---------------start------------->8---
(let (helper) ; temporary variable (not buffer local)
(with-current-buffer buffer-b
;; set it to `foo's binding in buffer-b
(setq helper foo))
;;back in buffer-a
(setq foo helper))
--8<---------------cut here---------------end--------------->8---
BTW, did you have a look at my example? I think it's quite close to
what you want to achieve.
Michael.
