commit https://github.com/vim/vim/commit/169ebb080454357279ad5ad21ac532deaec605e8 Author: Bram Moolenaar <Bram@vim.org> Date: Wed Sep 7 23:32:23 2016 +0200 patch 7.4.2344 Problem: The "Reading from channel output..." message can be unwanted. Appending to a buffer leaves an empty first line behind. Solution: Add the "out_msg" and "err_msg" options. Writing the first line overwrites the first, empty line.

" 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
