bug#65823: 30.0.50; sexp mismatches

[Andreas Röhler]

;; Buffer in emacs-lisp-mode.

(defun foo (arg)
  "(Some command \"]\" )  ( "
  ;; ( asdf
  (interactive "p*")
  (message "%s" arg))

;; In example code above go into docstring at opening parenthesis from 
"(Some".
;; M-x forward-sexp RET will match the closing bracket, not the closing
;; parenthesis.

;; Also, when starting from closing parenthesis in docstring, it does 
not get
;; the opening.


;; Second:
;; With cursor at comment line, at open paren before asdf:

;; M-x forward-sexp RET matches the end of defun outside comment.
;; But from there backward-sexp doesn't reach the starting point.

;; Forward- and backward-sexp should correspond WRT of the position reached.

;; When sexp navigation starts from inside a string or comment, it
;; should match only in respective environment.
