[development] A bug in 4.7b2 which won't be fixed

[Karoly Negyesi]

Hi!

I have already submitted a patch which stops $user->data going oversize,  
basically it will add an unset($form_values['_account']) to  
user_edit_submit, so that the huge _account key won't be saved.

But for 4.7b2 and HEAD users, who already have $user->data blown up, they  
need a different thing:

$form_values['_account'] = NULL

and this will never get into the core because there is no reason to. So  
add this statement, and when the patch lands, remove it.

Regards
