This update improves the solution so that it doesn't step on other
minibuffer echo-area messages when it has nothing to report
(defun my-org-mode-post-command-hook ()
"Show POINT's \"help-echo\" information in the echo area.
This could be information about an org-link at POINT, or some other data."
(let ((message-log-max) ; suppress output to *Messages* buffer
(msg (get-text-property (point) 'help-echo)))
(when msg
(ignore-errors
(message "%s" (url-unhex-string msg) nil t)))))
