我与其他 3 名开发人员在一个团队中工作，大部分时间我们都在匿名分支中的同一个 Mercurial 存储库上工作，并定期与默认分支合并。昨天，其他开发人员之一决定更新到以前的版本并从那里继续工作。在提交他的更改然后拉取和合并之后，我们注意到 TortoiseHg 中的图表（见下图）出现了一些我们以前从未见过的奇怪行为。基本上，我们有一些图形线不以点结尾，但只是拖尾而不会合并回任何其他分支。这在简单的英语中是什么意思？
更新：我倾向于“错误”，但在最新的图表中，我有一条类似的线穿过整个图表，似乎根本没有任何用途。在这里，可以在图表最底部的变更集 0 左侧以浅蓝色看到它。
更新： hg glog 的 ASCII 输出如下所示。TortoiseHg 图在 rev 281 附近有未连接的线，但在这里看起来很好。所以……虫子？
