Users (who aren't whitelisted) who post top-level to an proposal should have their comment automatically moved to a PR review comment

还没有人认领这个 Issue。

The Spec Core Team often has the manual task of cleaning up comments that appear from contributors at the top-level of the MSC (a PR comment, rather than a PR review comment). Cleaning them up involves copying the contents of the comment, hiding it, then starting a new thread on the MSC (typically at line 1) and pasting the contents there as a quote. Along with some text to inform the user as to why it was necessary.

This is time-consuming manual work. And sometimes when we don't catch these comments quickly enough, other people will reply with another top-level comment, making the problem worse.

It would be nice if mscbot could take care of doing that automatically, along with a canned explanation. It should support a config option that excludes certain users (SCT, guardians, MSC author) who occasionally do need to post top-level from the correction.

Issue 中没有指定文件、测试或入口点。首先定位处理 GitHub pull-request comments 和配置的代码，然后跟踪顶层评论和用户排除是如何表示的。完成的标准是：符合条件的评论会连同预设说明一起移入 review threads，而被排除的用户不受影响。
