Aggregate nested comments into a single comment line during tabulation to avoid parsing errors related to strange whitespace. For comments, correct indentation is only enforced up to the nested indentation level. Mixing of tabs and spaces within the start of a comment (up to the first non-space character) is still disallowed. Closes gh-11
