Just checked, D'Arcy never told us. But it doesn't matter, the manpage
lies. I just tested it with a tiny little program that copies two
different constant strings into a buffer. Nothing get's padded with nulls,
as Tom knew. Once again, experience trumps book knowledge. (Checking
a couple random examples from my own code, I seem to have lucked out:
I've a habit of zeroing my buffers myself)
