.vimrc

" Important vimhelp topics for understanding vimrc:
"  - initialization ('startup')
"  - options ('option-list' for a terse summary of all) / guioptions
"  - set_env
" See how vim was compiled with :version.
" See all values that differ from defaults with :se all
" See an option's current value with :se {option}?
"  (To see where it was last set, use :verb se {option}?)
" Browse options with :opt
" Help on an option shadowed by a command via :help '{option}'
" Spaces in string options must be escaped!

" The existence of ~/.vimrc causes 'compatible' to be unset, so we note
" the 'virtual' set nocompatible via a comment here.
"set nocompatible

" Disable reading .vimrc, .exrc from the current directory. This was the
" default last I checked (vim 7), but important enough to make explicit.
set noexrc

" Turn on additional checks for exrc and friends. See trojan-horse. 
set secure

" Modelines are vim commands embedded into a file, setting options for that
" file. They're generally better handled via filetype support. Weaknesses
" have historically been found in VIM modeline support allowing execution
" of arbitrary code (trojaned text files) -- leave them disabled.
set nomodeline

" 'autoindent' is rather naïve and turning on filetype-specific indentation
" (via "filetype indent on") is usually a better choice. Debian prior to
" 2008-08 turns it on.
