Re: Incorrect path grammar test 'paths-data-20-f.svg'

Hi

Both of those lines look correct to me.

   - "comma-wsp" basically means comma and/or whitespace (
   https://www.w3.org/TR/SVG/single-page.html#types-CommaWSP ). So the
   first line is okay.
   - The second one is missing any comma or whitespace between some
   parameters, so is supposed to fail.
