vim-patch:9.1.0344: Cursor wrong after using setcellwidth() in terminal (#28391) 

Problem:  Cursor wrong after using setcellwidth() in terminal
          (mikoto2000)
Solution: output additional spaces, so the behaviour matches the GUI
          (mikoto2000)

fixes: vim/vim#14539
closes: vim/vim#14540

Fix CUI `setcellwidths` characters draw behavior to same GUI behavior.

This is already fixed and tested in Nvim in #28322.
