Let's see...  it's this slightly cryptic little function:

(defun Buffer-menu--pretty-file-name (file)
  (cond (file
         (abbreviate-file-name file))
        ((bound-and-true-p list-buffers-directory))
        (t "")))

The second clause there returns this:

"/home/larsi/src/emacs/trunk/lisp/"

which, as we can see, is not abbreviated.  I've now changed it on the
trunk to abbreviate these, too.
