I am not really sure this improves readability enough to add the churn
into the code. mempool is not the heaviest modified file but still,
making style changes without any further changes in the area are usually
quite weak to justify. They are just adding an additional hop in git
blame tracking without a good reason. Sure sometimes the end code is so
much easier to read that the change is worthwhile but I do not see it
here.

Others might think differently though.
