2000-09-12 Not Zed <NotZed@HelixCode.com>
* message-thread.c: Reverted to version 1.15.
(remove_node): Ok, if a node has a parent, remove it from the
parent list, otherwise remove it from the (supplied) root list.
(group_root_set): When we merge children, free the lost node.
(thread_messages_free): Remove the return, run as is.
