      Split the class/func block starting at `start_index` in a source code (defined by `lines`) into *inner blocks*.
  
      The block's header is included as the first element. The contiguous regions (without empty lines) that are not
      inside any inner block are included as blocks. The contiguous regions of empty lines that are not inside any inner
      block are also included as (dummy) blocks.
  
      Args:
          lines (`List[str]`):
              The source code, represented by a list of lines.
          start_index (`int`):
              The starting index of the target class/func block.
          end_index (`int`):
              The ending index of the target class/func block.
          indent (`int`):
              The indent of the class/func body.
          backtrace (`bool`, *optional*, defaults to `False`):
              Whether or not to include the lines before the inner class/func block's header (e.g. comments, decorators,
              etc.) until an empty line is encountered.
  
      Returns:
          `List[Tuple[str, int, int]]`: A list of elements with the form `(block_name, start_index, end_index)`.
