Luuk van Baal 3a1973debc vim-patch:9.0.0672: line partly shows with 'smoothscroll' and 'scrolloff' zero
Problem:    Cursor line only partly shows with 'smoothscroll' and 'scrolloff'
            zero.
Solution:   Do not use 'smoothscroll' when adjusting the bottom of the window.
            (closes vim/vim#11269)
