The count is supposed to just count short blocks, not errors. This is a
POSIX requirement. I installed the attached documentation patch to try
to make this clearer.
The documentation improvement was added here:
https://git.savannah.gnu.org/cgit/coreutils.git/commit/?id=59e01d13e600be0d2c7f08f3aff8cf11936b3ea1
Perhaps dd should output a separate line to stderr that summaries I/O
errors; it could do that without violating POSIX.
Marking this as a wishlist item.
