patch 8.0.0430: options test fails or hangs on MS-Windows commit https://github.com/vim/vim/commit/bb962262eb6b18d93161d7506317d215ae80bfe5 Author: Bram Moolenaar <Bram@vim.org> Date: Wed Mar 8 00:01:35 2017 +0100 patch 8.0.0430: options test fails or hangs on MS-Windows Problem: Options test fails or hangs on MS-Windows. Solution: Run it separately instead of part of test_alot. Use "-S" instead of "-u" to run the script. Fix failures.
