AFAIK "don't use spaces" only applies to the first line of a statement.
When breaking long lines using spaces to align to the containing
parenthesis is quite common (though I don't like it personally).

The rule for follow-up lines is only: Descendants are always
substantially shorter than the parent and are placed substantially to
the right.
