Comment (by peterwilsoncc):

 [attachment:"49956.2.diff"] includes feedback on the pull request.

 * `Cache-control` and `Expires` HTTP headers used in response for
 unapproved comments.

 I realised I made a key typo on my previous comment around ensuring only
 single requested comment is displayed...

 If a user posts a reply to their own unmoderated comment, **neither** the
 parent or new comment will display. The new comment is considered an
 orphan and the comment walker discards it. I don't know of a good fix for
 this, suggestions are welcome.
