That certainly makes it clearer. (And I'm amazed that I missed the 
"indicator" entry while reading the form-fu documentation). Just one 
quibble: Shouldn't the comment
# Since we set indicator, we should only end up here if we
# have a username in the form

come AFTER this if?
  if ($login_form->submitted_and_valid) {

Or am I completely misunderstanding how and where indicator is used?
