Makes sense to me. Looking at REG_EQUAL notes in hash_scan_set is
something relatively new. Your patch fixes something we appear to have
overlooked.
I'd still like to see the before/after dumps. While I think the patch
is reasonable as well, those dumps should make it clearer to anyone
looking at this in the future what was going on -- particularly
important since we don't have an in-tree port which exhibits this problem.
