  # This chunk just adds a marker (with a custom name) to the generated Ruby and only attempts to
  # transfer the corrections it receives to the indentation of the associated lines.
  #
  # Also used so that Rubocop doesn't think that there is nothing in `if` and other such structures,
  # so that it does corrections that make sense for the HAML.
