Linting completely breaks when asked to confim a substitution with inccommand turned on.

Starting a substitution with :%s:::c while inccommand is set to either split or nosplit completely messes up linting and highlighting. Replacements don’t have to actually be confirmed, simply initiating a substitute command causes problems.

Replacing items without the c flag in the substitution, or with set inccommand= behaves as expected.

inccommand is nosplit by default, check :h inccommand. I can’t reproduce your issue.

Sorry for the ::: issue, I made it wrong with two sign.

Here’s my test.

mini.vim

set nocompatible
set runtimepath^=/Users/fannheyward/.local/share/nvim/plugged/coc.nvim
filetype plugin indent on
syntax on

set runtimepath^=~/src/coc-pyright

test code foo.py:

def foo(bar: int = None):
    bar = 1

steps:

1. nvim -u mini.vim foo.py
2. search bar
3. :%s:::c, without <cr> to confirm

two bar are removed. <cr> to confirm:

press n twice, no errors.

:set inccommand=nosplit, and :%s:::c again, press <cr> to confirm and n twice, no errors.
