    Copy non set positions as spaces

    st selection don't insert in the selection position whose value is not
    set. This is correct for the positions in the end of the line, but cause
    some problems in the beginning. For example echo -e 'a\tb' will print in the
    screen:

    a	b

    but after selecting and copying in some place you get:

    ab

    because positions from 1 to 7 don't have any value. This patch deals all
    positions without value as blank (even at the end of the line).
