>Description:
logname is a utility that prints the username on the standard output.
when doing: 'logname meuh', it returns my login name, when doing
'logname reel', it returns my login name, when I do 'logname -e', it
returns an error. As logname will always return the login whatever
the argument passed is, it still wants to know if we passed some
options to it. It doesn't have any options. Which means that it should
not normally call getopt() to see if there is options, as the next
switch only brings it to usage().
>How-To-Repeat:
Type: logname -e (or any other options...)
Note: logname --e will not give any errors.
>Fix:
Here is a patch:
