Moves @count characters 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 new position of
@iter is different from its original position, and dereferenceable
(the last iterator in the buffer is not dereferenceable). If @count
is 0, the function does nothing and returns %FALSE.
