'modeline' (singular), a Boolean option, defaults to off for root, see
":help 'modeline'".
Some people pretend that letting root use modelines is a security hole.
In the course of my use of Vim, I've seen many such supposed "holes"
plugged by disabling some options in modelines, and sandboxing others. I
don't think such a security hole, if there still is any, would remain
open any significant length of time after being discovered -- but maybe
I'm too optimistic there. Of course, no modelines also mean no help
syntax highlighting and no help hotlinking -- among other things.
Here's what I have in my vimrc about the use of modelines:
if exists("+modelines")
" the following is required because of SuSE's paranoid /etc/vimrc
" and to force 'modeline' on even for root in Vim 7.0.237 and later
set modeline modelines=5
" the following disables a dangerous modeline in one helpfile
if has ('autocmd')
au BufReadPost ada.txt setl nomodeline ft=help
endif
endif
Best regards,
Tony.
