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)
      "…some doc…. http and https schemes are supported;
    https is conditional on GnuTLS.")
