who - argv not checked for values ?

[Sujith Ramakrishnan Nair]

I saw some old track back on this subject, but nothing conclusive.
This is not a burning issue , but a minor irritant.

Why are we not checking for the values being passed for 2nd & 3rd options
when we are not invoking any options ?
See below.
