commit https://github.com/vim/vim/commit/e74e8e7d758e9312165a931f176185f07a64231a Author: Bram Moolenaar <Bram@vim.org> Date: Tue Feb 16 22:01:30 2016 +0100 patch 7.4.1342 Problem: On Mac OS/X the waittime must be > 0 for connect to work. Solution: Use select() in a different way. (partly by Kazunobu Kuriyama) Always use a waittime of 1 or more.

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
