With --continue, check stopped at the first file whose content or
checksum attribute it could not read, and at the first directory it
could not list. Each of these now counts as failed, its error, which
names the path, goes to stderr, and the walk goes on; the run still
exits non-zero. The count that sizes the progress bar leaves such a
path out, so the bar stays. The walk and the count, shared with sum
and clear, take the continue setting; those commands pass false and
still stop at the first error. Without --continue the first such error
still stops the run, and the summary printed before it now counts an
unreadable checksum attribute as failed, as it already did for
unreadable content.
