Hi,

Thanks for the patch.

I miss here however the most important information - why do you need it?
The answer to "why" should be in commit msg.

The change was kind of intentional and accepted, because revision ID is
printed next to the product ID. Printing revision ID with product ID
could be confusing...

Best regards,
Krzysztof
