私は他の3人の開発者とチームを組んでおり、ほとんどの場合、匿名ブランチの同じMercurialリポジトリで作業しており、定期的にデフォルトブランチとマージしています。昨日、他の開発者の1人が以前のリビジョンに更新し、そこから作業を続けることにしました。彼の変更をコミットしてからプルしてマージした後、TortoiseHgのグラフ（下の画像を参照）で、これまでに見たことのない奇妙な動作に気づきました。基本的に、ドットで終わらないグラフ線がいくつかありますが、それはただ引きずり出され、他のブランチにマージされることはありません。これは平易な英語でどういう意味ですか？
更新：私は「バグ」に傾いていますが、最新のグラフには、グラフ全体を通り抜ける同様の種類の線があり、まったく目的を果たさないようです。ここでは、グラフの一番下にあるチェンジセット0の左側に水色で表示されています。
更新：hgglogからのASCII出力が以下に表示されます。TortoiseHgグラフには、rev 281の周りに接続されていない線がありますが、ここでは問題ないように見えます。だから...バグ？
