does include_docs option in db.list work?

I try to change `include_docs` in db.list({ include_docs: false }) and it has no effect. Docs returned anyway.
I checked your package source and `include_docs` being used in one place and it's true always.

Does this option exist or not?

Start at the db.list entry point and trace how the include_docs option is handled, checking the reported call with include_docs: false. Done means the option changes the response so documents are omitted when it is false, with the existing behavior verified for the default or true case.
