Thanks for the explanation.

Anyway, I think it would make sense to add what you're requesting -- but

I didn't know how to answer, so I looked how other editors do. I found two
behaviors:

1. Unless the point is right by the parens, it should highlight the curly
braces. So in this case it would highlight the curly braces.

With the point in these places would highlight the parens, otherwise would
highlight the curly braces:

{|(|foobar}|)|

2. Ignore and don't highlight anything.
