First StyleComponentList should remove from 'auto' style.
This happens when there are no `--style` arguments other than the one passed in as a command line argument. Prior to this change, removing a style component (e.g. `--style=-numbers`) would remove the component from an empty style component set, resulting in no styles at all. That behaviour was less intuitive than the new behaviour, which starts out with the default components and removes the line numbers.
