What's the use case?

@sodatea My project use a private npm package, so i need to watch specific package in node_modules.

Could you try negated glob patterns to see if it overrides the default ignored patterns?
Something like ignored: ['!**/node_modules/**']

I just tested and it worked.

So let's just add a note in the documentation instead of adding a new option.
