Most Unices are a compromise between SysV and BSD (not OpenBSD, neither
FreeBSD, mind you) targeting POSIX conformability; in my experience [0],
none of the 'find' or 'xargs' commands I've used before GNU/Linux had
the -print0, -0 options.  POSIX 'find' does not require a -print0 option
[1], neither does the POSIX 'xargs' [2] require a '-0' one.

I have no experience with OpenBSD, FreeBSD though (which I won't
categorise as 'traditional' Unices), and I can see that emacs reports
your box as berkeley unix; I don't know which flavour though.

So, "...these are the GNU versions..." could be wrong or misleading, I
agree (but I believe it's not); I think that "...the traditional Unix
ones..." is correct though.
