I did ... not quite ... and waaaay back in 2004:

-rw-r--r--  1 stefan users     658 2004-03-16 09:30 vo_numbers.vim

As far as I can see, it only numbers a single level, as I am not a
friend of too many numbers in headings. But using the prefix mechanism,
you could generate nested numbers, too, I guess.

The following is totally unsupported, don't even think of asking me why
I did something the way I did. I haven't touched vimscript for years.

function! Number() range
  let l:prefix = input("Prefix: ")
  let l:postfix = input("Postfix: ", " ")
  let l:count = 1
  let l:indent = indent(a:firstline)
  let l:current = a:firstline
  while l:current <= a:lastline
    if indent(l:current) == l:indent
      let l:line = getline(l:current)
      let l:line_ = substitute(l:line, '^\(\t*\)\(.*\)$', '\1'.l:prefix.l:count.l:postfix.'\2', "")
      call setline(l:current, l:line_)
      let l:count = l:count + 1
    endif
    let l:current = l:current + 1
  endwhile
endfunction

function! Denumber()
  silent! s/^\(\t*\)[0-9.]* \(.*\)/\1\2/
endfunction

map ,,n :call Number()
map ,,N :call Denumber()

Have fun,
s.
