commit https://github.com/vim/vim/commit/9f8187c335b4fb07be9095dfdd0fc52670ba3c3f Author: Bram Moolenaar <Bram@vim.org> Date: Sat Aug 27 20:34:01 2016 +0200 patch 7.4.2272 Problem: getbufinfo(), getwininfo() and gettabinfo() are inefficient. Solution: Instead of making a copy of the variables dictionary, use a reference.

" Vim filetype plugin file
" Language:  systemd.unit(5)

if !exists('b:did_ftplugin')
  " Looks a lot like dosini files.
  runtime! ftplugin/dosini.vim
