body_content_lines ()

Ideally we should properly handle indentations of multiline snippet, but it’s not implemented yet since because we use result of this method only when it’s a single line and implementing the logic introduces additional complexity.

def body_content_lines
  raw_body_lines.map(&:strip).reject(&:empty?)
