Thanks. The original patch is much older than I thought --- I was
looking in the November/December part of the archives.

Yes, and that's what this does. Looking back, the original discussion
got a little confused because the TODO item about "order duplicate index
entries by tid" got brought into the mix. Actually this patch has
nothing to do with that, because it only acts during btree creation not
during index updates.
On inspection I have no problem with the patch, only with the comments ;-)
If you like I'll revise the comments and apply.
