public bool backward_visible_lines (int count)
Moves count
visible lines backward, if possible (if count
would move past the start or end of the buffer, moves
to the start or end of the buffer).
The return value indicates whether the iterator moved onto a dereferenceable position; if the iterator didn’t move, or moved onto the
end iterator, then false is returned. If count
is 0, the function does nothing and returns
false. If count
is negative, moves forward by 0 - count
lines.
