echo -ne '\012' is not that bad, and parsing array of integers from
kernel will be an ugly piece of code.

Anyway I don't care much, either byte array or ascii array of integers
is fine with me. (But I was under impression that after /proc
experiences, the latter is forbidden; I might be wrong.
/data/l/linux-good/Documentation/sysfs-rules.txt should be updated).
