[Fedora-packaging] Packaging guidelines for Emacsen add-on packages

[Ville Skyttä]

Regarding the current Emacsen add-on draft,

* Added some more info about requiring a version of (X)Emacs newer than or 
equal to the one used to compile the *.elcs, and how to find that version out 
dynamically during package build.

* I'd like to see something mentioned about packaging *.el snippets that 
aren't full blown packages of their own, see for example rpmdevtools.
