commit https://github.com/vim/vim/commit/920694c1b60fac8017b8909efcc24f189804a9bb Author: Bram Moolenaar <Bram@vim.org> Date: Sun Aug 21 17:45:02 2016 +0200 patch 7.4.2236 Problem: The 'langnoremap' option leads to double negatives. And it does not work for the last character of a mapping. Solution: Add 'langremap' with the opposite value. Keep 'langnoremap' for backwards compatibility. Make it work for the last character of a mapping. Make the test work.
