[Nix-dev] Treating emacs24-nox as an alternative to emacs

[Aristid Breitkreuz]

Try something more like this:

{
    packageOverrides = pkgs:
     rec
     {
       emacs = pkgs.emacs24-nox;
       djr = pkgs.buildEnv {
           name = "djr";
           paths = with pkgs; [emacs mu];
       };
     };
}
