patch 8.0.1688: some macros are used without a semicolon

commit https://github.com/vim/vim/commit/6f4700233fd925fe122b851f937929fb5e5da707
Author: Bram Moolenaar <Bram@vim.org>
Date:   Tue Apr 10 18:47:20 2018 +0200

    patch 8.0.1688: some macros are used without a semicolon

    Problem:    Some macros are used without a semicolon, causing auto-indent to be
                wrong.
    Solution:   Use the do-while(0) trick. (Ozaki Kiichi, closes #2729)
