I've gotten confirmation that my copyright assignment info is all 
up-to-date, so once this patch passes muster, it should be ok to merge it.

I'm not sure if someone has a better idea for how to do things, but for 
my config[1], the patch works well and makes CC modes behave the same as 
other programming modes. In my opinion, the worst thing 
`electric-pair-mode' can do is to behave inconsistently, since that 
forces the user to pay close attention to something that should be 
almost invisible/automatic.

[1] I customize `electric-pair-inhibit-predicate' to disable 
electric-pairing in strings/comments, and this patch interacts correctly 
with that customization.
