commit https://github.com/vim/vim/commit/f2c4c391192cab6e923b1a418d4af09106fba25f
Author: Bram Moolenaar <Bram@vim.org>
Date: Fri Jul 29 20:50:24 2016 +0200
patch 7.4.2117
Problem: Deleting an augroup that still has autocmds does not give a
warning. The next defined augroup takes its place.
Solution: Give a warning and prevent the index being used for another group
name.
