commit https://github.com/vim/vim/commit/f9f22dbe4f90673ecce601a9dee4bb750ce3cd8f Author: Bram Moolenaar <Bram@vim.org> Date: Sun Apr 3 14:09:59 2016 +0200 patch 7.4.1701 Problem: Equivalence classes still tested in old style tests. Solution: Remove the duplicate.

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
