This is because a sector is now not considered bad until it has been 
tried in a single-sector read. I think this is more accurate that 
marking 128 non-trimmed sectors as bad just to mark 127 of them as good 
later.

'errors' begin counting just after the copying phase, so they are not 0 
to the end. But you are right that now they start counting later.

Please, tell us what is the effect you want to achieve. If 
--max-error-rate or --exit-on-error don't do what you need, maybe 
--max-errors can be extended, or a new option can be implemented.

'errsize' is the sum of the sizes of all the bad-sector blocks. (In 1.19 
also of non-trimmed and non-scraped blocks). In your case the mean size 
of the bad areas seems to be about 4 KiB.
