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). closes: #13034 Signed-off-by: Christian Brabandt <cb@256bit.org> Co-authored-by: Tim Pope <vim@tpope.org>
