Likely caused by using shr to render the reply inside an HTML blockquote tag. Maybe we need to duplicate newlines, or replace them with br tags. What do you think?

[progfolio]

Replacing newlines with "<br>" gets us part of the way there in ement-room--render-html:

-  (insert string))
+ (insert (replace-regexp-in-string "\n" "<br>" string))

But that will also replace newlines in a reply's already formatted HTML, so it doesn't seem like the right solution to me.
Haven't had much time to dig into the source, but is there a way to separate the quoted portion of a reply from the body of the actual reply?

Yes, but that is more easily handled by #150, which I want to merge soon, but haven't had time to test. If anyone wants to test that and provide feedback, it would help.
