[PLUG] Emacs: removing obsolete assoc.el

[Rich Shepard]

   Running emacs-24.5 here. This morning when I started emacs I saw the
message that package assoc is obsolete, so I did a web search. Found that,
indeed, it was deprecated with 24.2 and the package is apparently called
assoc.el. One contributor on the emacs wiki provided a script to find all
his git packages that require assoc.el, but that's not relevent to me.

   Looking for the package on my system using 'find / -name assoc.el'
returned nothing.

   While the deprecation warning does not stop use of emacs I would like to
remove assoc.el when I can find it.

   Thoughts?
