I do not think this is important enough to justify a back-patch.

How so? The counter will increase after there's some actual work done,
ie building an index. If there's no indexes to build then it hardly
matters, because the command will complete in very little time.

Well, we could fix that if we made TOTAL be the total number of
descendants rather than just the leaves ;-). But I think not
incrementing is probably better.
