Following nh2's advice, I want to be more involved in nixpkgs,
and I'll start to review changes to programs that are important to me,
and that didn't have a long list of maintainers yet.

Motivation for this change

Things done

• Tested using sandboxing (nix.useSandbox on NixOS, or option sandbox in nix.conf on non-NixOS linux)
• Built on platform(s)
  • NixOS
  • macOS
  • other Linux distributions
• Tested via one or more NixOS test(s) if existing and applicable for the change (look inside nixos/tests)
• Tested compilation of all pkgs that depend on this change using nix-shell -p nixpkgs-review --run "nixpkgs-review wip"
• Tested execution of all binary files (usually in ./result/bin/)
• Determined the impact on package closure size (by running nix path-info -S before and after)
• Ensured that relevant documentation is up to date
• Fits CONTRIBUTING.md.

Note: I got the feeling that nix-shell -p nixpkgs-review --run "nixpkgs-review wip" didn't do anything sensible. See the command line output:

$ nix-shell -p nixpkgs-review --run "nixpkgs-review wip"
$ git -c fetch.prune=false fetch --force https://github.com/NixOS/nixpkgs master:refs/nixpkgs-review/0
