Is this identical to #11788? If so, this is fixed only on master because
it was deemed too risky for emacs-25. I'm still of the opinion that this
is a serious security issue, because of the possible silent fallback to
http without the user noticing. I'm always running my Emacs with
3c623c26a manually backported.
