Hi Sky,

A minor nit from my side.

If you need to respin this patchset for some other reason, please consider
preserving reverse xmas tree order - longest line to shortest - in this
function.

Likewise there are a few other changes in this patch which look like they
could be trivially updated to preserve or adopt reverse xmas tree order.

Edward Cree's tool can be of assistance here:
