patch 8.1.1055: CTRL-G U in Insert mode doesn't work for shift-Left commit https://github.com/vim/vim/commit/75bf3d22f42684beecd977f3185e98045b5c33d9 Author: Bram Moolenaar <Bram@vim.org> Date: Tue Mar 26 22:46:05 2019 +0100 patch 8.1.1055: CTRL-G U in Insert mode doesn't work for shift-Left Problem: CTRL-G U in Insert mode doesn't work to avoid splitting the undo sequence for shift-left and shift-right. Solution: Also check dont_sync_undo for shifted cursor keys. (Christian Brabandt)
