Neat, in time for 0.3, thank you!  :-)

I just added it to Emacs:

... and it actually built directly.  :-)

Now, the widgets that use Pango for font rendering (I suppose), like
menus, display squares instead of actual characters, and the console is
filled with things like:

I guess we’ll need a pseudo-package that creates a fonts.conf file for a
given set of fonts, like
<https://github.com/NixOS/nixpkgs/blob/master/pkgs/development/libraries/fontconfig/make-fonts-conf.nix>.
