  <!-- Detect indentation with at most 4 symbols:

  Indentation level:

  - -   key: value

  - -   value
       value
  # ^ final indent

  Captures spaces at the start of a line as well as spaces between -, : and ?.
  The captures between symbols are in 2 parts:
  - a single space which replaces the symbol in the dynamic construction rules
  - and the spaces which follow

     -   -   - bla
  ~~~         capture 1
      ~   ~   capture 2 and 4
       ~~  ~~ capture 3 and 5
     ^   ^    replaced with capture 2 and 4 for dynamic indent

  The empty capture at the end is necessary to ensure
  that the number of captures is always at least 9.
  Otherwise, %N in dynamic rules are not replaced with empty string. -->

      @{ No indented text

      Normally, `lineEndContext` should be set to `#stay`,
      but this prevents the embedding of code blocks such as Markdown:

      ```
      text
      continuation (LvL0 context)
      ``` <- continuation also (LvL0 context, no top level context),

      This is not compliant and displays incorrectly in some cases:
