If you don't have access to Perl, you can do it directly from VIM by calling this function:
function! Listing()
" set line numbers in front of lines
let i=line("$")
let pre = ' '
while (i > 0)
if match(i, '^9*$') == 0
let pre = pre . '0'
endif
call setline(i, pre . i . "\t" . getline(i))
let i=i-1
endwhile
endfunction

Why not filter through UNIX cat command ? In vim you could simply type:
- %!cat -n
and you got line-numbers for each line of the file.
