commit https://github.com/vim/vim/commit/b20e334859334be35de4b295023a2b49bdabbfa9
Author: Bram Moolenaar <Bram@vim.org>

patch 7.4.1131
Problem: New lines in the viminfo file are dropped.
Solution: Copy lines starting with "|". Fix that when using :rviminfo in a
function global variables were restored as function-local
variables.
