This issue is simply when managing content from the admin section at admin/content/node.
The original issue was that the ?destination= in the edit links from that page were breaking the $form_state['redirect'] option in the submit handler.
I used a simple unset($_REQUEST['destination']) to avoid this, and allow the Save & Edit button to work properly.
The issue now is that I'm trying to reattach the original ?destination= value to the $form_state['redirect'] so that eventually, after they actually save or publish the node, it WILL redirect them back to the proper admin/content/node rather than the node view page.
Minor issue, but still needs to be worked out.
