Provide a minimal init.vim/vimrc with less than 50 lines (Required!)

call plug#begin('~/.vim/plugged')

How to reproduce the problem from neovim/Vim startup (Required!)

edit a python source file
type in a 'if ... elif ...' snippet
observe the odd indention at keyword 'elif'

Generate a logfile if appropriate

export NVIM_PYTHON_LOG_FILE=/tmp/log
export NVIM_PYTHON_LOG_LEVEL=DEBUG
nvim -u minimal.vimrc
some works
cat /tmp/log_{PID}

I have figured out the cause is in the function deoplete#util#indent_current_line():

function! deoplete#util#indent_current_line() abort
  let pos = getpos('.')
  let len = len(getline('.'))
  let equalprg = &l:equalprg
  try
    setlocal equalprg=
    silent normal! ==
  finally
    let &l:equalprg = equalprg
    let pos[2] += len(getline('.')) - len
    call setpos('.', pos)
  endtry
endfunction

The 'equalprg' still affects though it is setted to null locally in fact, please confirm whether this is the original intention.

Thanks
