Senseless churn is frowned upon.  Ya know, the gratuitous knob-polishing
some folks like to do that unintentionally introduce subtle bugs because
the result isn't tested (and often not found until long after).

If you're working in an area and it warrants cleanup then one hopes
you're also testing.  That's fine but as stas requested please commit
the changes separately.
