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.

/*
 * An extremely simple program to make the cursor blink in an xterm.
 * This is useful when the cursor is hard to spot in a highlighted file.
 * Start in the background: "blink&"  Stop by killing it.
