Don't auto-continue > quotes on newlines (for the new formatting preview feature)

Or make it optional.

What I mean is, if the current line is a > quote, and I press shift-enter, it automatically keeps the next line as a quote, which for me is super frustrating.

It's especially annoying that it does this when pasting text. The way you've done formatting previews generally makes me very happy, but I keep considering disabling it because of this.

I do know that I can press backspace after, or press shift-enter 3 times, but I would really, really appreciate just not having this or being able to disable it.
