OK, thanks. So I got this now:
Here is what I would do instead:
(defun empty-line-p (&optional ispec)
"Returns t if cursor is at an empty line, nil otherwise.
Displays result in minibuffer when called interactive."
(interactive "p")
(save-excursion
(beginning-of-line)
(save-match-data
(let ((res (looking-at empty-line-p-chars)))
(or (and ispec
(message "%s" res))
res)))))
