commit https://github.com/vim/vim/commit/62ef797496c6243d111c596a592a8ef8c1d1e710 Author: Bram Moolenaar <Bram@vim.org> Date: Tue Jan 19 14:51:54 2016 +0100 patch 7.4.1137 Problem: Illegal memory access when using :copen and :cclose. Solution: Avoid that curbuf is invalid. (suggestion by Justin M. Keyes) Add a test.

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
