Should make it even easier to use custom channels, because whenever the
user does a "nixos-rebuild --upgrade", it will also upgrade possibly
used ("used" as in referenced in configuration.nix) channels besides
"nixos". And if you also ship a channel tied to a particular version of
nixpkgs or even remove the "nixos" channels, you won't run into
unexpected situations where the system is not updating your custom
channels.

This is very useful if you want to distribute channels (and thus
expressions as well) in a similar fashion to Debians APT sources (or
PPAs or whatnot).
So, for example if you have a channel with some additional functions
or packages, you simply add that channel with:
sudo nix-channel --add https://example.com/my-nifty-channel foo
And you can access that channel using <foo>, for example in your
configuration.nix:
{
imports = [ <foo/modules/shiny-little-module> ];
environment.systemPackages = with import <foo/pkgs> {}; [ bar blah ];
services.udev.extraRules = import <foo/lib/udev/mkrule.nix> {
kernel = "eth*";
attr.address = "00:1D:60:B9:6D:4F";
name = "my_fast_network_card";
};
}
Within nixpkgs, we shouldn't have <nixos> used anywhere anymore, so we
shouldn't get into conflicts.

Needed to be able to run 'make serve' in a pelican directory, else this
happens:
$ make serve
cd /home/bfo/pelican-test/output && python -m pelican.server
/run/current-system/sw/bin/python: No module named markupsafe
make: *** [serve] Error 1
That way sending mail with mutt works on NixOS too, without having to
manually change mutt's config on your system. sendmail will be found in
$PATH at runtime, and thus the setuid wrapper will be used, if
available.
Regression introduced by 56a6f22d7fb4690871669eba38a30e4f5a8cb483.
I'm temporarily pulling in test_mccabe.py, as suggested by someone at
flintwork/mccabe#31, which for now should fix the build (and the tests
of course as well).
