        correct usage of the test utility
    
        According to POSIX, when called with one argument, test(1) shall
        behave as follows: Exit true (0) if $1 is not null; otherwise, exit
        false.
    
        Consequently, this behaviour is correct:
    
         $ test -n
         $ echo $?
        0
         $ test -n ""
         $ echo $?
        1
