OK, I maybe should have suggested adding a preference.
But if you live in a world of paired parentheses (and I thought Emacs-Lispers 
were!) you want to add them in pairs, always.

I haven't done the work of surveying pairing packages.
I just happened to pick up electric-pair-mode from a specific package (I forget 
which), and since it is a global thing, it immediately started affecting all my 
buffers.  It is nice enough, so I kept it on.  
But the behavior I was fixing here is seriously jarring (as in *always* wrong) 
in my usage.
