Bug#844164: vim: since version 8, vim ignores indentation settings in /etc/vim/vimrc.local

[Mikulas Patocka]

Package: vim
Version: 2:8.0.0022-1
Severity: normal

Dear Maintainer,

*** Reporter, please consider answering these questions, where appropriate ***

   * What led up to the situation?
I want to set up indentation rules that I am used to.
On vim7, it is possible to modify indentation rules in
/etc/vim/vimrc.local, but on vim8, most of the settings in
/etc/vim/vimrc.local are ignored.

   * What exactly did you do (or not do) that was effective (or
     ineffective)?
I have this /etc/vim/vimrc.local file:
set nocp
set autoindent
set nocindent
set backupcopy=auto,breakhardlink
set bs=indent
set t_Co=1
hi ModeMsg term=none
hi NonText term=none
hi SpecialKey term=none
hi MatchParen term=none
syntax off
filetype off
filetype plugin off
filetype indent off

   * What was the outcome of this action?

Vim8 ignores some of the above settings
Vim automatically turns on the "cindent" rule if the file has "c"
extension (despite the fact that there is "filetype off" and "nocindent").

The command ":set backupcopy" shows "backupcopy=auto" (the breakhardlink flag is ignored)
The command ":set bs" shows "backspace=indent,eol,start" (the setting should be just "indent")
The command ":filetype" shows "filetype detection:ON  plugin:ON  indent:ON" (it should be turned off)


   * What outcome did you expect instead?
Vim should honor the configuration file /etc/vim/vimrc.local
