"ignore: {}" causes restricted functions and imports to be ignored

In HLint 2.2.2, the following config:

- ignore: {}
- functions:
  - {name: putStrLn, within: []}
- modules:
  - {name: [Data.List], as: List}

causes no warning to be issued on the following module:

module Main where
import Data.List as L
main :: IO ()
main = putStrLn $ L.intercalate " " ["hlint", "is", "awesome"]

whereas the appropriate warnings are raised without the ignore: {}. This is counterintuitive to me, because the README says:

These directives are applied in the order they are given, with later hints overriding earlier ones.
