        '%%' is only available in the non-readline-version.

        The last 10 command lines are available using the following
        '%%'-commands:

        '%%?'           displays the last 10 command lines.

        '%%i'           displays the command line with number i 
                        (0 <= i <= 9). 
                        This line can be edited.

        '%%'            displays the last command line.
                        This line can be edited.
                        ('%%' is equivalent to '%%0'.)

        '%%'-commands are not possible in sequences and loops.
