Use the correct filename when applying settings to an empty buffer

[cxw42]

When running in an autocmd, % is not necessarily the buffer the autocmd applies to. Instead, it turns out you have to use <afile> and <abuf> for that (ref.). Therefore, change all the references to % to refer to the relevant buffer by number.

Additionally, for consistency, replace setlocal calls with setbufvar() calls to the numbered buffer. That way, all the changes will affect the same buffer.

Fixes #208.

Just in case, are you expecting review?

[cxw42]

@xuhdev would you be willing to try this branch and see if it works for you? I have been pretty much AFK on personal projects since I opened this :( . Please let me know either way. Thanks!

[xuhdev]

Could you rebase the changes? Looks like I have no permission to push the rebased change.

[xuhdev]

I also tested the changes locally and I haven't encountered any problems with either named or unnamed buffers.

[cxw42]

@xuhdev thanks! I have rebased/resolved/force-pushed. I am going to run with this branch for a little bit just in case I missed anything, and then merge the PR.

Hi, recently I have an issue with editorconfig-vim after this PR merged.

test.vimrc:

set nocompatible

call plug#begin()
Plug 'editorconfig/editorconfig-vim'
Plug 'junegunn/fzf', { 'dir': '~/.fzf', 'do': './install --all' }
call plug#end()

autocmd FileType c EditorConfigReload

.editorconfig:

root = true

[*]
tab_width = 8

test.c:

#include <stdio.h>

int main() {
  int x = 1;
  printf("%d\n", x);
  return 0;
}

How to reproduce the problem:

• Run vim -u test.vimrc test.c
• Place the cursor anywhere except the first column
• Run :FZF
• Press Esc to close the popup
• The cursor goes to the first column of line 1

I couldn't reduce test.vimrc further as I don't know much about popup windows. I've also run git bisect, and it pointed e269673.
