Emacs package guidelines introduce unnecessary deps

[Michael Cronenworth]

Upon upgrading a F17 box today I notice "desktop-file-utils" wants to 
pull in "emacs-filesystem". When I investigate the cause I find it to be 
the Emacs packaging guidelines.

The guidelines now force any package that has Emacs add-ons to install 
them in the main package and Requires: emacs-filesystem. Emacs is not 
installed by default and I do not use Emacs, nor will I ever. I'm not 
sure why having sub-packages was such a negative thing. Can we bring 
back sub-packages?
