26.2; documentation error in elisp/Regexp-Functions node |

The documentation under "Function: regexp-opt" says:
The resulting regexp of regexp-opt is equivalent to but usually more efficient
than that of a simplified version:
(defun simplified-regexp-opt (strings &optional paren)
(let ((parens
(cond
((stringp paren) (cons paren "\\)"))
((eq paren 'words) '("\\<\\(" . "\\)\\>"))
((eq paren 'symbols) '("\\_<\\(" . "\\)\\_>"))
((null paren) '("\\(?:" . "\\)"))
(t '("\\(" . "\\)")))))
(concat (car paren) ;; BUG: should be parens, not paren?
(mapconcat 'regexp-quote strings "\\|")
(cdr paren)))) ;; BUG: should be parens, not paren?
---------------------------------------------------------------------------
The expressions on the third last line and the last line should be (car parens)
and (cdr parens), no?

Yes, thanks.
It was fixed in the sources a while ago and it's already correct in
26.2.90, the current pretest release for 26.3.
You can download a source tarball of 26.2.90 here:
