bug#55202: 27.1 Feature request: Show parens when point is anywhere inside of them

[José Júnior]

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.

I guess 2) seems more consistent, but I don't have much of an opinion.
Choosing one or the other of the parentheses seems a bit arbitrary.
