commit https://github.com/vim/vim/commit/7ce686c990ea8c490d16be7f1c6bd95eb48816f9 Author: Bram Moolenaar <Bram@vim.org> Date: Sat Feb 27 16:33:22 2016 +0100 patch 7.4.1430 Problem: When encoding JSON, turning NaN and Infinity into null without giving an error is not useful. Solution: Pass NaN and Infinity on. If the receiver can't handle them it will generate the error.
