If an element has defines #parents upfront, then form_builder() takes the #parents as base for #array_parents.

I do not have an actual bug to showcase this, but while debugging #414424: Introduce Form API #type 'text_format', I realized that this situation can occur.

Um. The original made no sense. My fault. It was written very late in D6 cycle, beta 3 time alas :/ so it was faulty. Oh well.

It also needs documentation: #279246: FAPI #array_parents is not documented

It's not on http://api.drupal.org/api/drupal/developer--topics--forms_api_reference....

Committed to CVS HEAD. Marking it as 'code needs work' for a documentation follow-up per #2.
