Merge branch 'blockquote-fence-filter' into 'master'
Add blockquote fence syntax to Markdown
Fixes https://gitlab.com/gitlab-org/gitlab-ce/issues/16564
Before Markdown rendering happens, this will transform this:
```
Let me quote this here email:
>>>
Dear friend,
How are you?
Greetings,
Me
>>>
```
Into this, saving me from having to prefix all of those lines with `>` manually when I copy some multiline text from another medium:
```
Let me quote this here email:
> Dear friend,
>
> How are you?
>
> Greetings,
>
> Me
```
