Well, the middleware does try not to respond with a full response when
it gets an XMLHttpRequest. I tells this because of X-Requested-With:
XMLHttpRequest. Another thing that suppresses the full response is a
GET variable _. If you want, we would accept a patch that checks the
Accept header and also uses that to give shortened errors (you could
look for those other checks as a place to introduce a new check).
