Quote link not being added to comments in complex setup.

Hi,

I have a very complex setup for my comments, using advanced_forum, comment_block, contexts, all on top of drupal commons. For some reason menu_get_object() was not aware of the $node->comment value in this setup.

I don't know the exact problem, where menu_get_object() is failing, but I fixed this by changing to a node_load().

Here is a simple patch for this fix. Probably only necessary if you're have a very complex setup, and quote links don't appear for unknown reasons.

Should this be the default mechanism for grabbing the comment's node?
