The standard localization argument against concatenating an "s" onto a
word does not apply here. But, one day, someone is going to grep for
occurrences of http:// to see if it’s still used anywhere.
That someone could be you.
Spell it out.
(defvar …-elpa-root
(if (gnutls-available-p)
"https://elpa.gnu.org/packages/";
"http://elpa.gnu.org/packages/";)
"…some doc…. http and https schemes are supported;
https is conditional on GnuTLS.")
