patch 8.2.3709: Vim9: backtick expression expanded when not desired Commit: https://github.com/vim/vim/commit/fad2742d538123abb9b384a053fd581f2acf6bb0 Author: Bram Moolenaar <Bram@vim.org> Date: Tue Nov 30 21:58:19 2021 +0000 patch 8.2.3709: Vim9: backtick expression expanded when not desired Problem: Vim9: backtick expression expanded when not desired. Solution: Only expand a backtick expression for commands that expand their argument. Remove a few outdated TODO comments.

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
