Oh, indeed, sorry for being dense.
That's indeed a bug. You could try to work around it with something like:
(defvar lua-font-lock-syntactic-keywords
'(((lambda (limit)
;; font-lock sometimes fails to erase the `syntax-table' property before
;; calling us. So let's make sure it's clean before moving on.
(remove-text-properties (point) limit '(syntax-table))
nil))
(lua-match-multiline-literal-bounds
(1 "!" nil noerror)
(2 "|" nil noerror))))
Also, I recommend you use syntax-propertize-function when available.
It comes with various advantages (e.g. it also works when font-lock is
disabled).
Stefan
PS: BTW, do you have any news about the copyright status of lua-mode
that would prevent including it in GNU ELPA?
