Instead of going through the updates one by one, not knowing what's ahead (not even how many), I'd rather like to see the updates printed in advance, and then letting the user choose which updates to comment on (e.g. by typing number 12 to comment on an updated marked with [12]). After the user has picked favorite updates, the rest can be offered to be mass-skipped or mass-ignored.

Of course the next-next-next workflow should be kept as well (e.g. "Press Enter to go through updates one by one, or type a number to select a specific one: ").
