new lines should be treated as spaces

[stoyan]

body
div
{color: red}

gives

{ type: 'rule',
  selectors: [ 'bodydiv' ],
  declarations: [ { type: 'property', name: 'color', value: 'red' } ] }

I think the selector should be body div

Does it make sense to convert \n => <space> in selectors, or just leave any \n as is since they are not necessarily invalid characters?

Makes sense, you're right.
