Not entirely true: FreeBSD's implementations of find and xargs,
which are not from GNU, have these options. I think this is also
true of NetBSD.

...unless it's an old unix vendor's xargs (hello, Sun!), which will
clamp at 512 arguments and/or 512 (or if you're lucky, 5120) bytes
per command line because nobody ever modified them to realize they're
not on 7th research edition any more.
