I wanted to review the output of this first patch side-by-side so that I
do not have to go through all the markup hell.  But when I tried looking
for the artefacts from any possible pipeline this could have run through
I was greeted with a "get off my lawn" message.  So if you are okay with
me just skimming through the first patch (after reviewing the rest of da
patch series), then with the mentioned fixes, this is for you (xkcd#276)
