Batch output in terminal when running hook_update confusing

I have the output cleaned up when not using batches

Processed item_1. [8%] [1/12]
Processed item_2. [16%] [2/12]
Processed item_3. [25%] [3/12]
Processed item_4. [33%] [4/12]
Processed item_5. [41%] [5/12]
Processed item_6. [50%] [6/12]
Processed item_7. [58%] [7/12]
Processed item_8. [66%] [8/12]
Processed item_9. [75%] [9/12]
Processed item_10. [83%] [10/12]
Processed item_11. [91%] [11/12]
Process completed: Bullwinkle annoyed Rocky with 12 out of 12 jokes.

still working on the batched variety.

And now batched items look like this

drush codit-batch-operations:run TestDo10Things --allow-skip
Processed item_1,item_2,item_3. [30%] [3/10]
Processed item_4,item_5,item_6. [60%] [6/10]
Processed item_7,item_8,item_9. [90%] [9/10]
Process completed: Bullwinkle annoyed Rocky with 10 out of 10 jokes.

This is merged and will go out with Beta1
