patch 8.0.0369: a few options are not defined, depending on features commit https://github.com/vim/vim/commit/c43a8b8de0676caf8a460b6af1310d7aba8221bb Author: Bram Moolenaar <Bram@vim.org> Date: Sat Feb 25 21:12:29 2017 +0100 patch 8.0.0369: a few options are not defined, depending on features Problem: The 'balloondelay', 'ballooneval' and 'balloonexpr' options are not defined without the +balloon_eval feature. Testing that an option value fails does not work for unsupported options. Solution: Make the options defined but not supported. Don't test if setting unsupported options fails.
