Deal with indentation gaps

[buschtoens]

When you leave blank lines without the proper indentation between two properties css-whitespace fails. This is a problem, becaue many code editors automatically remove the whitespace in otherwise empty lines.

css-whitespace should ignore those lines, i.e. remove every line that only contains whitespace: css.replace(/\s+\n/gm, "");

css.replace(/[^\S\n]+\n$/gm, "") looks better. Now it seesm to work. I also auto remove all \r, because they aren't stripped out by css-whitespace.

function parse(css) {
  return rework(
    whitespace(
      css.replace(/(?:[^\S\n]+\n|\r)$/gm, "")
    )
   ).toString();
}
