I tested also busybox's implementation and looked at Heirloom's and
FreeBSD's version. It seems to be the consensus not to create an empty
output file. It is the most natural thing to do in the natural
algorithm.

The description in the '-l' option is also not helpful.

Maybe file a defect at austingroupbugs?

My Coreutils 8.20 and Busybox don't seem to do that. The GNU one seems
to stat the file for some reason, Busybox does not. I think that this
tool should not need to care about permissions, like 'sed "1w file"'.
