RuboCop::Cop::MultilineExpressionIndentation#left_hand_side

In a chain of method calls, we regard the top send node as the base
for indentation of all lines following the first. For example:
a.
  b c { block }.            <-- b is indented relative to a
  d                         <-- d is indented relative to a
