10744	autosaves deletes content for hidden meta_fields on custom widgets/plugins	hertzel	azaozz	"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
