Problem

Command :EditorConfigDisable, which although not present in the documentation, and setting (manually via Vim Command mode and via ".vimrc") buffer variable (:let b:EditorConfig_disable = 1) don't disable plugin.

Steps to reproduce

1. Open a test file containing only one string "test"
2. Try to disable the plugin using a command or variable
3. Enter Insert mode, add some extra spaces at the end of the line and return to Normal mode
4. Save the file by typing :w

And after that all extra spaces from the end of the line are removed, which indicates that the plugin is still working. I even tried to run Vim (vim -u ./.minimal_vimrc ./test.txt) and Neovim (nvim -u ./.minimal_vimrc ./test.txt) with a minimum config (all files are below), but the plugin still wasn't disabled.

My configuration

• OS: Windows 10
• Vim version: 8.2.5117
• Neovim version: 0.8.1
• Vim plugin manager: vim-plug
• Neovim (sources Vim config) plugin manager: packer.nvim

Minimal config "./.minimal_vimrc"

call plug#begin('~/AppData/Local/nvim/plugged')
Plug 'editorconfig/editorconfig-vim'
call plug#end()

"./.editorconfig" file

root = true
