Set the local key the same as global and poof you can :)  course you can't 
tell what keys have global defaults and what don't.

But there is no way for an application to know if there is a global key that 
needs to be deleted before its default is used.

That works solution will work for me :)

Sounds good to me.  I can already think of several dozen places I need to 
change to use that once it is added.

Why doesn't the application just set it to false, "", etc.  The global config 
are simply another default layer with no other powers the adding and deleting 
off stuff from the config level should always take place in the local.  Yes 
they should be viewed as merged, but following the priorities level.  I think 
that the deleteEntry should remove the line rather then adding the [$d], but 
will transition all my deleteEntry() to a different function if that is what 
you all decide.
