applied, thanks! With some opinionated line-reduction as follow-up (opinionated
because it was OK as is too, and I could have noticed that on the previous
review, sorry...)

Did not think it through at all, but maybe it makes sense to add the uploaded
size also to the upload stats.

And FWIW, I slightly changed my mind and now think that having the reused
counter also printed might indeed be nice, but as mentioned in the v2 reply,
we can always extend this and starting out simpler is OK – if users directly
request this you get a free told-you-so coupon applicable to me directly
though ;-P
