nolintlint does not detect an unused // nolint:... directive, when the corresponding linter is disabled

[manoranjith]

Consider the below snippet, where the nolint directive is unused for typecheck linter.

package main

import "fmt"

func main() {
	var a int // nolint: typecheck
	fmt.Println(a)
}

If we enable typecheck and nolintlint linters, then golangci-lint reports an error:

$  golangci-lint run --enable nolintlint  --enable typecheck ./...
main.go:6:12: directive `// nolint: typecheck` is unused for linter "typecheck
" (nolintlint)
        var a int // nolint: typecheck
                  ^                                                   

But, if we disable typecheck and enable nolintlint, it does not report an error.

$ golangci-lint run --enable nolintlint --disable typecheck ./...  

However, in this case as well the nolint directive is unused by any of the linters.
Is this the expected behavior ? Will it possible to configure the nolintlint to throw warning in the second case as well ?
