Farid Zakaria fbf42c55ac nix-shell --pure: Let it work for any derivation ... `nix-shell --pure` when applied to a non stdenv derivation doesn't seem to clear the PATH. It expects the stdenv/setup file to do so. This adds an explicit `unset PATH` by nix-build.cc (nix-shell) itself so that it's not reliant on stdenv/setup anymore. This does not break impure nix-shell since the PATH is persisted as the variable `p` prior in the bash rcfile fixes #5092		2021-08-06 15:30:49 -07:00
