netstat arg parser not warn about unused arguments

Binary package hint: net-tools

Seems netstat uses only command line options (-t or --tcp for example) and not uses arguments at all.
But command line parser not warn about it

For example:

$ netstat -atn # works fine

$ netstat atn # my misstake- I forgot '-'
-- output is idential just 'netstat', argument 'atn' is silently ignored.

Expected:
netstat must warn about incorrect command line arguments.
