}

CommentsOptions defines the way comments are going to be written- has_nl: adds an newline at the end of a list of comments

• same_line: line comments will be on the same line as the last statement
• level: either .keep (don't indent), or .indent (increment indentation)
• prev_line: the line number of the previous token to save linebreaks
