Block Quote Styling?

Hi all-

The block quote styling I'm getting in Mattermost bugs me, and I'm curious if anyone else knows what's going on. The Markdown documentation page included in the install (available here on Github) shows block quotes rendered with a thick vertical bar. This is what it looks like on my screen:

but in Mattermost it always renders a large double quote character:

Is there a simple way to change the behavior? (I'm also not crazy about the larger font used for block quotes, but that's less distracting to my eye than the quote icon...)

(Only slightly related, the in-situ screenshot above is a situation where I'd really like mattermost to render double quoting a little nicer, e.g:

>> first speaker
> second speaker

Thanks!
