these changes were generated with nixq 0.0.2, by running nixq ">> lib.mdDoc[remove] Argument[keep]" --batchmode nixos/**.nix nixq ">> mdDoc[remove] Argument[keep]" --batchmode nixos/**.nix nixq ">> Inherit >> mdDoc[remove]" --batchmode nixos/**.nix two mentions of the mdDoc function remain in nixos/, both of which are inside of comments. Since lib.mdDoc is already defined as just id, this commit is a no-op as far as Nix (and the built manual) is concerned.
