[Suggestion]: Allow Detached Modifiers without Content.

-
- second list item

Several reasons:

• More consistent writing experience. When user type - in line start, they will immediately see the list item bullet. Even there aren't any content after the prefix.

  - <|cursor|>

  `--- parsed as unordered list item prefix (even without following *content* tokens)
  

• Allow list as first child of quote case:

  • list items
  • under quote

  In markdown:

  > - list items
  > - under quote
  

  With this proposal:

  >
  -- list items
  -- under quote
