OK, I found what I wanted. We made rules fire in alphabetical order in
7.3, and INSTEAD rules are not reordered to the font/back --- they are
treated just like any other rule and executed alphabetically.
I thought we had some problem with rules or triggers and OLD/NEW
handling, but I can't see any mention of that, and it must have been in
an older release.
The question of firing order is a good one and one that isn't asked very
often.
