doc: clarify the printable characters output by od
* src/od.c (usage): Mention any printable character is output,
Not just ASCII.
* doc/coreutils.texi (od invocation): Further clarify that only
single byte characters are output (due to the alignment requirement).
Also mention the fact that 3 digit octal sequences are output
for non printable characters without a corresponding C escape.
