    There's a cautionary note in the Vim help files that has to do with
    ".exrc" files in directories other than $HOME; those get read as default
    behavior unless "secure" is set in EXINIT or "~/.exrc" (note that this
    is standard for "vim"; I _believe_ it's also standard for "vi" but have
    no way to test at the moment.) A user opening up an untrusted tarball is
    all it would take.
