vim-patch:9.1.1836: 'culopt' "screenline" not redrawn with line("w0") and :retab

Browse Source 
Problem:  'cursorlineopt' "screenline" isn't redrawn when moving cursor
          and then using line("w0") and :retab that does nothing.
Solution: Call redraw_for_cursorcolumn() when setting a valid w_virtcol
          (zeertzjq).

closes: vim/vim#18506
