I pushed this PR using this patch 😄

[oliverpool]

After downloading the patch, I adjusted my home-manager config to get it working with nix:

  programs.lazygit =
    let
      patchedPackage = pkgs.lazygit.overrideAttrs
        (finalAttrs: previousAttrs: {
          patches = [ ./assets/lazygit-4018.patch ];
        });
    in
    {
      enable = true;
      package = patchedPackage;
      settings = {...};
    };

(would be nicer if this PR could be merged, but in the meantime I get an updatable patched lazygit 🎉 )
