commit https://github.com/vim/vim/commit/f9c8bd2137b045f9a64d63eefcf022b4726b1419 Author: Bram Moolenaar <Bram@vim.org> Date: Tue Dec 29 21:34:48 2015 +0100 patch 7.4.998 Problem: Running tests in shadow directory fails. Test 49 fails. Solution: Link more files for the shadow directory. Make test 49 end up in the right buffer.
