bug#42484: 26.1: org-mode should display value of links in minibuffer

[Boruch Baum]

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)))))
