patch 8.2.4384: Vim9: error message not tested, some code not tested Commit: https://github.com/vim/vim/commit/bc510064027da8024d59460c9c816aea4ffac096 Author: Bram Moolenaar <Bram@vim.org> Date: Mon Feb 14 21:19:04 2022 +0000 patch 8.2.4384: Vim9: error message not tested, some code not tested Problem: Vim9: error message not tested, some code not tested. Solution: Add a couple of test cases. Give an error for a command modifier without a command.

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
