I have the same comment for this function as the earlier similar 
function, although given the function signature here it does seem 
obvious that it's really meant to list partitions on multiple devices. 
How does the user invoke that from the command-line? Hmm, it looks like 
"ide part" works differently (prints for all devices) than "part list" 
(which works on a single user-specified device); odd..
