patch 8.0.0198: some syntax arguments take effect even after "if 0" commit https://github.com/vim/vim/commit/de318c5c35ed0d65fd2a07196cb8acd5ee6d9bf8 Author: Bram Moolenaar <Bram@vim.org> Date: Tue Jan 17 16:27:10 2017 +0100 patch 8.0.0198: some syntax arguments take effect even after "if 0" Problem: Some syntax arguments take effect even after "if 0". (Taylor Venable) Solution: Properly skip the syntax statements. Make "syn case" and "syn conceal" report the current state. Fix that "syn clear" didn't reset the conceal flag. Add tests for :syntax skipping properly.
