patch 8.2.4120: block insert goes over the end of the line Commit: https://github.com/vim/vim/commit/9f8c304c8a390ade133bac29963dc8e56ab14cbc Author: Bram Moolenaar <Bram@vim.org> Date: Mon Jan 17 17:30:21 2022 +0000 patch 8.2.4120: block insert goes over the end of the line Problem: Block insert goes over the end of the line. Solution: Handle invalid byte better. Fix inserting the wrong text.

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
