patch 8.0.1564: too many #ifdefs commit https://github.com/vim/vim/commit/f2bd8ef2b4507d02c6043affff8f7e85e3414d5f Author: Bram Moolenaar <Bram@vim.org> Date: Sun Mar 4 18:08:14 2018 +0100 patch 8.0.1564: too many #ifdefs Problem: Too many #ifdefs. Solution: Graduate the +autocmd feature. Takes away 450 #ifdefs and increases code size of tiny Vim by only 40 Kbyte.
