Ah, I finally understood the issue at hand! It's really hard to discuss indentation problems in e-mail. :D

Yeah, I can confirm there's a bug when using (setq ruby-align-chained-calls t) in this example:

some_variable.where.not(x: nil)
                         .where(y: 2)

The two `where`s should be lined up, but currently the second `where` is lined up with the `not`.

some_variable.where.not(x: nil)
                                    .where(y: 2)

I can also confirm that the first behavior is what RuboCop (Ruby's popular linter/formatter) expects, when configured for aligned chained method calls.
