 Steps to reproduce.

 1. create a new hidden meta field
 add_post_meta($post_id, "_hidden", "under the table", true)     or
 update_post_meta($post_id, $idx_item_name, $name);
 2. Create a regular meta field
 add_post_meta($post_id, "Survive", "HI Im alive",true) or
 update_post_meta($post_di, "Survive", "HI Im alive");

 using hook save_post
 they save and be retrieved just fine but after the first call to autosave,
 _hidden will be be saved with "" instead of the value passed to the hook
 function
