* This function is responsible for generating a comment reply form.
* There are several cases that have to be handled, including:
* - replies to comments
* - replies to nodes
* - attempts to reply to nodes that can no longer accept comments
* - respecting access permissions ('access comments', 'post comments', etc.)
*
* The node or comment that is being replied to must appear above the comment
* form to provide the user context while authoring the comment.
*
* @param $node
* Every comment belongs to a node. This is that node.
*
* @param $pid
* Some comments are replies to other comments. In those cases, $pid is the parent
* comment's cid.
*
* @return
* The rendered parent node or comment plus the new comment form.
