patch 8.2.0747: cannot forcefully close all popups Commit: https://github.com/vim/vim/commit/03a9f848175b182372fb33403998059724a8bf31 Author: Bram Moolenaar <Bram@vim.org> Date: Wed May 13 13:40:16 2020 +0200 patch 8.2.0747: cannot forcefully close all popups Problem: Cannot forcefully close all popups. Solution: Add the "force" argument to popup_clear(). Use it after running a test. Put back the check for a popup when editing a file.
