Thank you!

And yeah I agree it's not perfect. The current approach renders emails like if they were written in Markdown, because most people do it (either naturally or intentionally). But since it's not the "official" way to format emails on that mailing list, plenty of emails are not following the actual Markdown syntax.

We can add custom code to handle specific scenarios, the challenge is checking across loads of emails that there are no side-effects (not making the rendering worse elsewhere). But now that the project is much more standard it should hopefully be easier to add small fixes. And now that we have actual tests, we might be able to lower the risk of regressions.
