commit https://github.com/vim/vim/commit/45d2eeaad66939348893b9254171067b0457cd9d Author: Bram Moolenaar <Bram@vim.org> Date: Mon Jun 6 21:07:52 2016 +0200 patch 7.4.1903 Problem: When writing viminfo merging current history with history in viminfo may drop recent history entries. Solution: Add new format for viminfo lines, use it for history entries. Use a timestamp for ordering the entries. Add test_settime(). Add the viminfo version. Does not do merging on timestamp yet.
