Christian Clason ec753cf40d vim-patch:f7ac0ef50988 
runtime: don't execute external commands when loading ftplugins

This is a followup to 816fbcc262687b81fc46f82f7bbeb1453addfe0c (patch
9.0.1833: [security] runtime file fixes)

It basically disables that external commands are run on loading of the
filetype plugin, **unless** the user has set the `g:plugin_exec = 1`
global variable in their configuration or for a specific filetype the
variable g:<filetype>_exec=1.

There are a few more plugins, that may execute system commands like
debchangelog, gitcommit, sh, racket, zsh, ps1 but those do at least
do not run those commands by default during loading of the filetype plugin
(there the command is mostly run as convenience for auto-completion or
to provide documentation lookup).

"
" Instructions for enabling "matchit" support:
"
" 1. Look for the latest "matchit" plugin at
"
" http://www.vim.org/scripts/script.php?script_id=39
"
" It is also packaged with Vim, in the $VIMRUNTIME/macros directory.
"
" 2. Copy "matchit.txt" into a "doc" directory (e.g. $HOME/.vim/doc).
"
" 3. Copy "matchit.vim" into a "plugin" directory (e.g. $HOME/.vim/plugin).
"
" 4. Ensure this file (ftplugin/ruby.vim) is installed.
"
" 5. Ensure you have this line in your $HOME/.vimrc:
" filetype plugin on
"
" 6. Restart Vim and create the matchit documentation:
"
" :helptags ~/.vim/doc
"
" Now you can do ":help matchit", and you should be able to use "%" on Ruby
" keywords. Try ":echo b:match_words" to be sure.
"
" Thanks to Mark J. Reed for the instructions. See ":help vimrc" for the
" locations of plugin directories, etc., as there are several options, and it
" differs on Windows. Email gsinclair@soyabean.com.au if you need help.
