I put vlf.el by Mathias into elpa.
I rewrote it almost completely (bzr still has the original version at
revno 233).

it works for me.
I wish I knew how to hook it into files.el, but I don't...

vlf.el has 2 issues:

1. insert-file-contents hangs emacs (see `vlf-next-batch'):

    ;; replacing `erase-buffer' with replace arg to `insert-file-contents'
    ;; hangs emacs
    (unless append (erase-buffer))
    (insert-file-contents buffer-file-name nil vlf-end-pos end)

2. I have this:

    (define-key map [C-+] 'vlf-change-batch-size)

When I do C-+ (by pressing Ctrl, Shift, and the "+=" key to the left of
backspace), I get "C-+ is undefined".
when I do M-x vlf-change-batch-size RET, I get
"You can run the command `vlf-change-batch-size' with <C-+>"
The "+" in both messages is the same character (43, #o53, #x2b).
