Markdown nested lists are not indented properly

Prettier 1.9.2
Playground link

--parser markdown

Input:

# Markdown Test

* A lit item
    * Bitbucket markdown requires 4 spaces for nested list items (https://stackoverflow.com/a/37594372)
* Pretter indents to 2 spaces (tab width doesn't seem to affect it)

Output:

# Markdown Test

* A lit item
  * Bitbucket markdown requires 4 spaces for nested list items (https://stackoverflow.com/a/37594372)
* Pretter indents to 2 spaces (tab width doesn't seem to affect it)

Expected behavior:

The nested list items require 4 spaces for proper display formatting in Bitbucket (likely others. see this SO https://stackoverflow.com/editing-help#advanced-lists )

It seems like prettier doesn't even respect tab-width for this :(

FYI, the reason why we did not respect tabWidth/useTabs, see #3223 and #3463 (comment).

The markdown renderer used by BitBucket is really weird... I'm not sure what should we do here, see #3531 (comment).

What would be the downside of simply changing the nested lists indentation from 2 to 4?

Docs: https://bitbucket.org/tutorials/markdowndemo/overview#markdown-header-lists

I'll submit a feature/bug to their Jira and see what comes of it. I think a few links to widely-used parsers (common mark, GitHub, and SO) could help sway them. Lists aren't the only things that get screwy in Bitbucket md, but they're certainly the biggest pain points when I bring docs in from other sources.

In the meantime, would it be such a big deal to infer the intent of nested list items and just make the indention 4 spaces (or two - give us a setting)?

After second thought, we can respect tabWidth here.
