Markdown vetter/formatter/prettifier. Messy markdown goes in, CommonMark comes out.

Features

• 80char lines (in lists and quotations as well, properly wrapped)
• right spacing between headers, code blocks
• normalized bullets (e.g., 1. 1. 1. vs 1. 2. 4.)
• possibly fixing some DWIMs in markdown and converting them to CommonMark?
  • or providing a stricter migrate command that would warn on suspicious/ambiguous cases and suggest the CommonMark alternative?

🎨 Prior art

• Prettier already does a decent job at formatting
  • but it doesn't keep the content width constant at 80-chars tho
