I remember that it used to scroll horizontally on mobile and was actually surprised when I saw the GP comment was wrapped even though it was formatted as code. Not sure whether I haven’t noticed the change before or if I saw it but forgot about it – either way I think it must be a relatively recent change.

I still prefer code formatting to only be used for code snippets, commands and command outputs though.

For quotes I like leading each quoted paragraph with a “>” sign and a space. Like we do in plain text emails. Same kind of thing that they talk about in http://catb.org/jargon/html/email-style.html
