Minor Moodle.org sites are served via https. It would be logical to update all links to moodle.org sites to https equivalent.
So, have to performe everywhere in moodle code some search/replace, like :
Perhaps just don't modify file mod/lti/tests/locallib_test.php where on line 177 you find:
$this->assertEquals('https://moodle.org', lti_ensure_url_is_https('http://moodle.org'));
Update script should update the docroot value in mdl_config table, when it's still the default one (http://docs.moodle.org).
Changes should also be done in language packs (but perhaps in another tracker item).
Dev documentation should also reflect this change.
You can also look at the related discussion.
