vim-patch:8.2.2495: text jumps up and down when moving the cursor

Browse Source 
Problem:    Text jumps up and down when moving the cursor in a small window
            with wrapping text and 'scrolloff' set.
Solution:   Adjust the computation of w_skipcol. (partly by Ghjuvan Lacambre,
            closes vim/vim#7813)
