IIUC the "... expands" feature only applies to some specific cases, not
for text inserted via `pp'.  Admittedly, it'd be good for those "..." to
be expandable in many more cases (ideally everywhere).

=====

1. I launch emacs-24 -Q and insert following form in scratch buffer:

    (let ((print-length 2) (print-level 3))
      (pp load-history (current-buffer)))

2. I navigate to a new line and press C-x e

    (("/usr/share/emacs/24.4/lisp/emacs-lisp/pp.elc" pp-escape-newlines ...)
     ("/usr/share/emacs/24.4/lisp/calendar/time-date.elc"
      (defun . with-decoded-time-value)
      ...)
     ...)

3. I navigate to previous line and place cursor between "." and "..)"
4. I press <RET> and ellipsis splits in two instead of expanding abbreviation
