Reverted to version 1.15. (remove_node): Ok, if a node has a parent,
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. svn path=/trunk/; revision=5352
