strange bug with gist over box and circle

If I create a gist index over a box and a circle, the index attributes
appear to both have type box.

I don't see any other, similar situations with other types, and I
haven't investigated the cause yet. Most similar situations work fine.

This is expected, no? Those opclasses use the STORAGE option.

I see, that makes sense. I was making the assumption that the types
matched in my new patch, and obviously that's incorrect.
