I'd personally prefer -0 because burning the -z short option may
be problematic for future extensions while the only use of
the -0 option in any program is "separate output by NULs".
But I'm game if you prefer -z.

thanks, then I'll keep it.

Interestingly, groups(1) doesn't seem to be specified by the
OpenGroup documents, only id(1):
  http://pubs.opengroup.org/onlinepubs/9699919799/utilities/id.html
Is there any other resource?

But I agree, outputting the "user:" prefix for only one argument
seems to be silly.

Thanks!

Have a nice day,
Berny
