Subject: Handle comments when indenting method chains

Previously, indentation went wrong when the comment on the line above
looked like a method call/member access:

    fn main() {
        // Lorem ipsum lorem ipsum lorem ipsum lorem.ipsum
                                                foo.bar()
    }

With this patch:

    fn main() {
        // Lorem ipsum lorem ipsum lorem ipsum lorem.ipsum
        foo.bar()
    }

Also, a blank line or a comment broke method-chain indentation:

    fn main() {
        something.a.do_it
        // A comment
            .aligned

            .more_alignment();
    }

With this patch:

    fn main() {
        something.a.do_it
        // A comment
                   .aligned

                   .more_alignment();
    }

Note that comments interleaving a method chain are not aligned with the
'.' of the method chain.
