Let me stick my hand up here: I'm the one who added automatic parens.

Yes, automatic parens don't work with square brackets. This is a symptom of the special treatment of square brackets when editing code, and I've suffered with this distinction for two or three years now.

More generally, the right fix is to rewrite this code in order to bring the round-square paren code (should this delimiter be square or round) together with the automatic paren code.

I agree that this is very irritating; I should fix it. With that said, I do believe the existing behavior is superior to the prior behavior.
