Reading through `org-store-link-functions' docstring and
`org-store-link' code, I noticed that `org-store-link-functions'
promises the following:

    Each function will be called in turn until one returns a non-nil

Yet, `org-store-link' does the following:

(dolist (f (org-store-link-functions))
		 (when (funcall f)
		   (push (cons f (copy-sequence org-store-link-plist))

(pcase results-alist
		  ;; Reinstate link plist associated to the chosen
		  ;; function.
		  (apply #'org-link-store-props
			 (cdr (assoc-string
                                (format "Store link with (default %s): " name)
                                (mapcar #'car results-alist)
                                nil t nil nil (symbol-name name))

That is, all the store link functions are actually being executed, not
until first non-nil return value. If multiple non-nil values are
returned, an interactive query is displayed to the user.


The actual behaviour is indeed nice, but I am wondering how it is going
to work in non-interactive case.
