patch 8.0.0188: redrawing for 'cursorbind' is inefficient commit https://github.com/vim/vim/commit/9506cad7a1a6e52a613f356de969cbd980815777 Author: Bram Moolenaar <Bram@vim.org> Date: Sun Jan 15 13:53:49 2017 +0100 patch 8.0.0188: redrawing for 'cursorbind' is inefficient Problem: Using NOT_VALID for redraw_later() to update the cursor line/column highlighting is not efficient. Solution: Call validate_cursor() when 'cul' or 'cuc' is set.
