31 * This function is responsible for generating a comment reply form.

33 * - replies to comments
34 * - replies to nodes
35 * - attempts to reply to nodes that can no longer accept comments
36 * - respecting access permissions ('access comments', 'post comments', etc.)
37 *
38 * The node or comment that is being replied to must appear above the comment
39 * form to provide the user context while authoring the comment.
40 *
41 * @param $node
42 * Every comment belongs to a node. This is that node.
43 *
44 * @param $pid
45 * Some comments are replies to other comments. In those cases, $pid is the parent
46 * comment's cid.
47 *
48 * @return
49 * The rendered parent node or comment plus the new comment form.
