Does not understand <nixpkgs> references

[nh2]

It seems it doesn't understand <variable> references yet, is that correct?

Works in nix-shell:

NIX_PATH= nix-shell -I nixpkgs=/etc/nixos/nixpkgs '<nixpkgs>' -A procps

Does not work in cached-nix-shell:

NIX_PATH= cached-nix-shell -I nixpkgs=/etc/nixos/nixpkgs '<nixpkgs>' -A procps

(I repro with NIX_PATH= to empty that variable, to avoid the <nixpkgs>' import potentially working due to some other system-dependent reason.)

Thanks for the report. Both #21 and #22 should be fixed in master branch.
