commit https://github.com/vim/vim/commit/b01f357791f88c7083e58cf2b36509dd83f21ea2 Author: Bram Moolenaar <Bram@vim.org> Date: Fri Jan 15 15:17:04 2016 +0100 patch 7.4.1091 Problem: When making a change while need_wait_return is set there is a two second delay. Solution: Do not assume the ATTENTION prompt was given when need_wait_return was set already.

" Vim syntax file
" Language:  systemd.unit(5)

if !exists('b:current_syntax')
  " Looks a lot like dosini files.
  runtime! syntax/dosini.vim
  let b:current_syntax = 'systemd'
endif
