But it does list their size, mode, and file -- just like list-buffers.

It works just like list-buffers:
Non-null optional arg FILES-ONLY means mention only file buffers.

Try the patches below, for both list-buffers and electric-buffer-list.
2004-10-04 Kevin Rodgers <ihs_4664@yahoo.com>
* buff-menu.el (list-internal-buffers): New option.
(list-internal-buffers): New command.
(list-buffers, list-buffers-noselect): Document and respect
new option.
2004-10-04 Kevin Rodgers <ihs_4664@yahoo.com>
* ebuff-menu.el (electric-buffer-list): Rename and document
optional FILES-ONLY prefix arg; document new
list-internal-buffers option.

It behaves the same as list-buffers. Try this:
(add-hook 'buffer-menu-mode-hook
(lambda () (set (make-local-variable show-trailing-whitespace) nil)))

Emacs is the extensible, customizable, self-documenting real-time
display editor:
(define-key electric-buffer-menu-mode-map "\C-h" 'Helper-describe-bindings)
