[Message part 1 (text/plain, inline)]

I've been using this workaround so far, and it seems to work (like the
first option, though):

(define-advice show-paren-function (:around (fn) fix)
  "Highlight enclosing parens."
  (cond ((looking-at-p "\\s(") (funcall fn))
        (t (save-excursion
             (ignore-errors (backward-up-list))
             (funcall fn)))))

I don't know about efficiency, but I haven't tried it in deeply nested
blocks.
