Docs don't make it clear whether rules in overrides merge or replace the main rules object

[callumlocke]

The Configuration based on glob patterns section only shows a single rule "quotes" being set and then overridden, and (AFAICT) it's not possible to tell from this example or the accompanying text if the rules for overrides are merged into the base rules object, or if it replaces it completely. Same for env and other objects.

I know the main config merged over any extended shared configs, so I'm guessing it's the same logic for overrides merging into the main config, but it would be good to state this clearly and/or update the example so it's more obvious.

Thanks for the issue. Would you mind making a new issue in the github.com/eslint/eslint repo? The documentation actually lives in that repo. Thanks!
