It cannot complete when complex lines exists in vim filetype

[mopp]

What I faced

The line auto completion does not work on some vim files. The other completion candidates also disappear in the case.

How to reproduce

I've used neovim.

:version
NVIM v0.10.0-dev-1299+g9abced6ad
Build type: Release
LuaJIT 2.1.1695653777

let s:dein_base = '~/dein/'
let s:dein_src = '~/dein/repos/github.com/Shougo/dein.vim'
execute 'set runtimepath+=' .. s:dein_src

call dein#begin(s:dein_base)

call dein#add(s:dein_src)

call dein#add('Shougo/ddc-filter-matcher_head')
call dein#add('Shougo/ddc-filter-matcher_vimregexp')

call dein#end()

Reproduced. But it is feature of ddc.vim.

  " NOTE: If the input text is longer than 'textwidth', the completed text
  " will be the next line.  It breaks auto completion behavior.

[Shougo]

Fixed. Please update ddc.vim.
