Re: [O] What does the _ in `(defun org-element-section-parser (_) ...)'

I guess it is a required signature for the function (i.e. some other
function will call it with some argument), and _ indicates it is not
used in the body. If you were to give it the arg a name, then checkdoc
would complain about it not being in the docstring.
