Issue

<Ctrl-Space> doesn't work as expected at all. I've tried it in insert mode and in normal mode.

Steps to reproduce

• Install vim-plug:

  curl -fLo ~/.vim/autoload/plug.vim --create-dirs \
  https://raw.githubusercontent.com/junegunn/vim-plug/master/plug.vim

• Change ~/.vimrc to this one:

  :set number relativenumber
  call plug#begin()
  Plug 'davidhalter/jedi'
  call plug#end()

• Restart vim
• Run :PlugInstall
• Restart vim
• Open any python file (with .py extension)
• Enter insert mode and type print(
• Press and obtain E29: No inserted text yet

Output of “:verbose JediDebugInfo”

My ~/.vimrc is wrong, it must be:

:set number relativenumber
call plug#begin()
Plug 'davidhalter/jedi-vim'
call plug#end()
