[Mew-dist 15563] thread separator patch again, final ?

[NINOMIYA Hideyuki]

こんばんは	二宮@お四国 です

new thread separator patch for b90 です。

一応メッセージ数表示も正しく出るようにしてますが、
# のでスピード的に問題ないなら merge してほしいなぁ...
セパレータ行を search-foward で数えるというしょぼい方法しか
思いつけませんでしたので、スピードが落ちてるのではないかと思います。
そのへん検証いただけると有り難いです。> all α tester
