Bad use of varaible_get causes total failure

The module will not install correctly, nor will it allow you to login because of the following logic errors:

function securepages_prevent_hijack_enable() {
  if (variable_get('securepages_enable', FALSE) && variable_get('securepages_prevent_hijack', FALSE)) {
    _securepages_prevent_hijack_cookie();
  }
}

Setting the variable default to FALSE here means the cookie is never set, causing the admin to be immediately logged out.

/**
 * Implementation of hook_user().
 */
function securepages_prevent_hijack_user($op, &$edit, &$user, $category = NULL) {
  switch ($op) {
  case 'login':
    if (variable_get('securepages_prevent_hijack', FALSE)) {
      if (! isset($_SERVER['HTTPS'])) {

Same here.

Now, I realize while typing that I can correct this behavior by adding:

$conf['securepages_prevent_hijack'] = TRUE;

To settings.php, except that the documentation NEVER mentions this little fact.
