commit https://github.com/vim/vim/commit/156919f99afd1ac11d19d4270afbc1afb7245640 Author: Bram Moolenaar <Bram@vim.org> Date: Sat Oct 15 20:46:20 2016 +0200 patch 8.0.0039 Problem: When Vim 8 reads an old viminfo and exits, the next time marks are not read from viminfo. (Ned Batchelder) Solution: Set a mark when it wasn't set before, even when the timestamp is zero. (closes #1170)

Tests for complicated + argument to :edit command

STARTTEST
:$-1w! Xfile1
:$w! Xfile2
:edit +1|s/|/PIPE/|w Xfile1| e Xfile2|1 | s/\//SLASH/|w
:w! test.out
:e Xfile1
:w >> test.out
:qa!
ENDTEST

The result should be in Xfile1: "fooPIPEbar", in Xfile2: "fooSLASHbar"
foo|bar
foo/bar
