The following code will add brackets around new page links, but not URLs.

(defun emacs-wiki-make-link (link &optional name)
  "Return a Wiki link to LINK with NAME as the text."
  (let ((case-fold-search nil))
    (unless name
      (setq name (emacs-wiki-wiki-visible-name link)))
    (when (string-match "^\\[\\[\\([^]]+\\)\\]" link)
      (setq link (match-string 1 link)))
    (when (equal name link)
      (setq name nil))
    (cond
     (name
      (concat "[[" (emacs-wiki-link-escape link)
              "][" (emacs-wiki-link-escape name t) "]]"))
     ((string-match (concat "^\\(?:" emacs-wiki-url-regexp "\\)") link)
      (emacs-wiki-link-escape link))
     (t (concat "[[" (emacs-wiki-link-escape link) "]]")))))

Adding brackets to old ones might be more work, but you can probably
use a regexp search for planner-date-regexp and then make sure it's
not part of a [[link]] already... Hmm.

If you don't have a lot of pages, a keyboard macro or
query-replace-regexp would be easy to set up and control. If you have
a lot of pages, maybe something fancier with Emacs Lisp or Perl?
