function coder_upgrade_op_to_hook($node, $case_node, $hook, $parameters) {

  /*
   * Copy the case body to the new hook function.
   * Insert before (or after) the $item function.
   *
   * When case body is empty (e.g. insert, update), then use next reference
   * until a non-empty body is found.
   *
   * TODO
   * Add the new function to the list of functions.
   * This is useful when we may need to check for the existence of a function
   * on another upgrade.
   * Example: hook_link() becomes part of hook_node_view()
   * or hook_comment_view() based on $type parameter. Also hook_link_alter()
   * code goes in hook_node_view_alter() or hook_comment_view_alter().
   * See http://drupal.org/node/224333#node_links.
