commit https://github.com/vim/vim/commit/888ccac8902cee186fbd47e971881f6d9b19c068 Author: Bram Moolenaar <Bram@vim.org> Date: Sat Jun 4 18:49:36 2016 +0200 patch 7.4.1895 Problem: Cannot use a window ID where a window number is expected. Solution: Add LOWEST_WIN_ID, so that the window ID can be used where a number is expected.
