What's missing from our changelogs

Ah, this looks good. I've been using the "find message ID" kind of thing when referencing email discussions, but it never occurred to me to include it in the tags section of the commit log.

But I think it would be better if this became more standard. Maybe if git itself would save the message ID so it could be easily looked up.

What we're missing here is a way to make it possible to find email discussions by looking at *any* commit in the git log. If there is a commit for which the message ID cannot be found in any public mailing lists, that would be a red flag telling us that the commit was not reviewed publicly.
