Another possibility is to copy all of the lines to the end of the
file (:copy $ instead of :copy 0 ). Then, having saved line("$")
before adding lines, you know how many lines to :move to the top.

Some time ago, answering a similar question on this list, I wrote the
Pippo() function and added it to foo.vim, my file of example vim
functions: http://www.vim.org/script.php?script_id=72
This is more of an index function than a table-of-contents function: it
searches for "words" (matching a given regular expression) and appends
them to the end of the file, one per line.
