This non-https link redirects to the https link already with a 301, so
the content is expectedly the same.

I doubt many people click on these links, as I guess they're usually
rendered as text so it depends on the editor, I expect as much as
anything it's 'advertising' or confirmation of the copyright notice.

But still, I've just clicked on them ... and I think this is a
reasonable step.
