Description:
        It seems that if the last member of an array is a null character, bash 
gets
        confused when expanding "@".  Characters following the output of 
${array[@]}
        are duplicated when echoed in certain circumstances. ie:

        $ a=('1' ''); echo "${a[@]}: "; echo "${a[*]}: "
        1 ::
        1 :
        $ echo "${a[@]}:: "; echo "${a[@]}::$"; echo "${a[@]}::>"
        1 ::::
        1 ::$
        1 :::>
