commit https://github.com/vim/vim/commit/4d585022023b96f6507e8cae5ed8fc8d926f5140 Author: Bram Moolenaar <Bram@vim.org> Date: Thu Apr 14 19:50:22 2016 +0200 patch 7.4.1740 Problem: syn-cchar defined with matchadd() does not appear if there are no other syntax definitions which matches buffer text. Solution: Check for startcol. (Ozaki Kiichi, haya14busa, closes https://github.com/vim/vim/issues/757)

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
