[bug introduced in coreutils-6.11]
+ dd cbs=N conv=unblock would fail to print a final newline when the size
+ of the input was not a multiple of N bytes.
+ [the non-conforming behavior dates back to the initial implementation]
+
df no longer requires that each command-line argument be readable
[bug introduced in coreutils-7.3]
