PATCH: minor fix for _uniq

["Jun T." <takimoto-j@xxxxxxxxxxxxxxxxx>]

Minor changes to the completion for 'uniq'.

Added an option -i for MacOSX (darwin) and freebsd,
and options -z/--zero-terminated for Gnu version.

I could not find options -t/--separator and -W/--check-fields in
my Linux boxes, but I didn't remove them.
