How to view/edit order item comments?

[Christian Carlow]

Comments can be added to order items when added to a shopping cart but 
cannot be edited afterwards.  At least on the shopping cart page the 
comments will appear as text just as the selected features do. However, 
once the order is created, the comments no longer appear. Is the 
comments field intentionally left out of the form?  Maybe having a 
textarea field for the comments in the form would make it too messy?
