I have been wrestling with the docs in these patches, which are somewhat
haphazardly spread across the various patches, and tying myself up in
knots. Fixing them so I don't cause later merge pain is difficult. I'm
therefore going to commit this series (staggered as previously
requested) without documentation and then commit a consolidated
documentation patch for them.
