[O] Wrong number of arguments: setq, 1

[Kaushal Modi]

Hi,

I needed to make these changes locally to make any kind of org export
(text, html, latex) work.

Without these fixes, I get an error like: Wrong number of arguments: setq, 1

I am not familiar with letrec but for let statements, if I want to set
a let-bound variable X's value to nil, I would do,

(let (X) ..)

or

(let ((X nil)) ..)

But NOT (let ((X)) ..) (Note the parentheses count).


Do the same rules not apply to letrec?

Here is my org-version:
