commit https://github.com/vim/vim/commit/ece61b06ef4726515177c9b293e1c20d2122a73f Author: Bram Moolenaar <Bram@vim.org> Date: Sat Feb 20 21:39:05 2016 +0100 patch 7.4.1373 Problem: Calling a Vim function over a channel requires turning the arguments into a string. Solution: Add the "call" command. (Damien) Also merge "expr" and "eval" into one.

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
