FWIW nothing to add from me.  Agree with Andy that we are down to style
things that would be good to tidy up before applying these.

Adding levels to switch nests always makes for ugly diffs so I fully agree
with Andy that, though trivial, it is probably better to do those in two steps
for ease of review.  If there is just one in a patch then meh, we can probably
cope with the extra thinking required to review them , but where it happens
several times it's worth making reviewer's lives that little bit easier!
