This would ideally be optional, as not everyone uses markdown, and I'm pretty sure there are markdown elements that would conflict with the *ledger format, but would it be possible to also associate the *.ledger filtetype with markdown?

Where a subset of markdown elements, that match *ledger comments characters, it would be great for folding (like #19) and enhanced comments/ notes etc,

Headers

• bullet
• lists

and maybe much more, if it can fly under the *ledger-comment-character radar.
