Hm, that was actually intentional because in this function now we
(mostly) have:

  do something with a
  do something with b
  			# something else I don't focus on at a glance

  do something with a
  do something with b

  # do something with a here? No, on the next line.
  # do something with b

But now that you mention it, I see it might be a questionable practice,
and I guess we could drop it.
