Once you say it like that, it makes sense. :)

Or rather, rerere should not take --renormalize at all.  Patch 11 below
has an explanation.

Jonathan Nieder (12):
  t6038 (merge.renormalize): style nitpicks
  t6038 (merge.renormalize): try checkout -m and cherry-pick
  t6038 (merge.renormalize): check that it can be turned off
  merge-trees: push choice to renormalize away from low level
  merge-trees: let caller decide whether to renormalize
  Documentation/technical: document ll_merge
  ll-merge: make flag easier to populate
  ll-merge: let caller decide whether to renormalize
  t4200 (rerere): modernize style
  rerere: migrate to parse-options API
  rerere: never renormalize
  merge-recursive --renormalize
