different complete behavier when open a file directly and enter nvim then use `e` command.

[lee-shun]

Hello!

my environment: nvim-0.9 + Windows 10 set shell? cmd.exe

• When I use nvim to directly edit an existing file with nvim the_file.vim, it was like:

• But when I enter nvim first and then use e the_file.vim it was like:

Apparently, for the same buffer, the completion items are so different!

I provide the following minimal config for you to debug:

1. init.vim

let $CONF_PATH = split(&runtimepath, ',')[0]
set runtimepath+=$CONF_PATH/dein/repos/github.com/Shougo/dein.vim

let s:dein_dir = $CONF_PATH.'/dein'
let s:dein_src = $CONF_PATH.'/dein/repos/github.com/Shougo/dein.vim'

call dein#begin(s:dein_dir)
call dein#add('prabirshrestha/asyncomplete-buffer.vim', {'lazy':1,
            \})

call dein#add('kitagry/asyncomplete-tabnine.vim', { 'lazy':1,
			\'build': 'powershell.exe .\install.ps1' })

let g:asyncomplete_conf = { 'lazy':1,
			\'depends': ['asyncomplete-tabnine.vim', 'asyncomplete-buffer.vim'],
			\'on_event': ['BufReadPre', 'BufNew'],
			\'hook_source':'let g:asyncomplete_auto_popup = 1',
			\'hook_post_source':'source $CONF_PATH/after_test.vim'}

call dein#add('prabirshrestha/asyncomplete.vim', g:asyncomplete_conf)

call dein#end()

filetype indent plugin on

if has('syntax')
	syntax on
endif

2. after_test.vim

function! s:check_back_space() abort
    let col = col('.') - 1
    return !col || getline('.')[col - 1]  =~ '\s'
endfunction

inoremap <silent><expr> <TAB>
            \ pumvisible() ? "\<C-n>" :
            \ <SID>check_back_space() ? "\<TAB>" :
            \ asyncomplete#force_refresh()
inoremap <expr><S-TAB> pumvisible() ? "\<C-p>" : "\<C-h>"

if dein#tap('asyncomplete-tabnine.vim')
    call asyncomplete#register_source(asyncomplete#sources#tabnine#get_source_options({
                \ 'name': 'tabnine',
                \ 'allowlist': ['*'],
                \ 'completor': function('asyncomplete#sources#tabnine#completor'),
                \ 'config': {
                \   'line_limit': 1000,
                \   'max_num_result': 4,
                \  },
                \ }))
endif
" buffer
call asyncomplete#register_source(asyncomplete#sources#buffer#get_source_options({
            \ 'name': 'buffer',
            \ 'allowlist': ['*'],
            \ 'completor': function('asyncomplete#sources#buffer#completor'),
            \ 'config': {
