This is no bug.  It's a user error.  If you want FileGroupContentsChange.sh 
to show
both files you either need to escape the '*' in the parameter your pass to 
it or have
the script process all the parameters (i.e. $*) with the internal 'ls' command.

That seems "classical" to me.  If you prefer 1 file per line, use the '-1' flag.
