Most configuration in postcss.config.js is ignored

The parser property in postcss.config is completely ignored.

Here's an example postcss.config.js of what I'd like to do:

module.exports = {
  parser: 'postcss-scss',
  plugins: [
    ...
  ]
}

Actually looking at the code, it seems like only the plugins array is used. This is the only reference to config in the whole file:

For those looking for a quick-and-dirty workaround, additional options can be added to the process call here:
