This seems fair when online, however I'm wondering whether it is when
offline. I'd say that the whole retry logic should be skipped in this
case? i.e. "if (block_retry || !online) { error message and continue }"
on both short read & checksum failure retries.

Patch applies cleanly, compiles, global & local make check ok.
I'm wondering whether it should exit(1) on "lseek" failures. Would it make
sense to skip the file and report it as such? Should it be counted as a
skippedfile?
WRT the final status, ISTM that slippedblocks & files could warrant an
error when offline, although they might be ok when online?
