patch 8.0.0190: finding duplicate tags uses a slow linear search commit https://github.com/vim/vim/commit/810f9c361c83afb36b9f1cdadca2b93f1201d039 Author: Bram Moolenaar <Bram@vim.org> Date: Sun Jan 15 16:52:51 2017 +0100 patch 8.0.0190: finding duplicate tags uses a slow linear search Problem: Detecting duplicate tags uses a slow linear search. Solution: Use a much faster hash table solution. (James McCoy, closes https://github.com/vim/vim/issues/1046) But don't add hi_keylen, it makes hash tables 50% bigger.
