patch 8.0.1259: search test can be flaky commit https://github.com/vim/vim/commit/13deab8d08145c1f6e2a3e82cb547bc7f87a3686 Author: Bram Moolenaar <Bram@vim.org> Date: Sat Nov 4 18:48:43 2017 +0100 patch 8.0.1259: search test can be flaky Problem: Search test can be flaky. Solution: Use WaitFor() instead of a delay. Make it possible to pass a funcref to WaitFor() to avoid the need for global variables. (James McCoy, closes #2282)
