I have not made a proper indent file out of this, but this is what I
use.  Before I work on BSD code I just run :call FreeBSD_Style().  The
IgnoreParenIndent() function is needed to avoid vim's built-in cindent
code when it comes to line-continuation after a parentheses.  Better
solutions are welcome.

---------------------------------------------

set nocompatible
set autoindent

" Let vim determine the file type to be edited.
"filetype plugin indent on

" Ignore indents caused by parentheses in FreeBSD style.
fun! IgnoreParenIndent()
 	let indent = cindent(v:lnum)

 	if indent > 4000
 		if cindent(v:lnum - 1) > 4000
 			return indent(v:lnum - 1)
 		else
 			return indent(v:lnum - 1) + 4
 		endif
 	else
 		return (indent)
 	endif
endfun

" Conform to style(9).
fun! FreeBSD_Style()
 	setlocal cindent
 	setlocal formatoptions=clnoqrt
 	setlocal textwidth=80

 	setlocal indentexpr=IgnoreParenIndent()
 	setlocal indentkeys=0{,0},0),:,0#,!^F,o,O,e

 	setlocal cinoptions=(4200,u4200,+0.5s,*500,t0,U4200
 	setlocal shiftwidth=8
 	setlocal tabstop=8
 	setlocal noexpandtab
endfun
