Respect bullet points in a similar way to language-markdown

[citizenrich]

Description

Would like similar behavior for bullet points as language-markdown, ie. indents and newlines respect * (bullet points) above them by continuing bullet points.

Reproduce:
Type a * on a newline.
Move to the next line or try to indent. Compare to language-markdown.
