You didn't mention .el files but you did write:

"When I bring up the electric buffer list, long file names are
truncated (with : at the end of the name).  This is a problem for me
since I'm used to using long source file names ... "

I use iswitchb and never electric buffer list but looking into it I found:

C-h f electric-buffer-list

"
electric-buffer-list is an interactive autoloaded Lisp function in
`ebuff-menu'.
(electric-buffer-list ARG)

Pop up a buffer describing the set of Emacs buffers.
Vaguely like ITS lunar select buffer; combining typeoutoid [*] buffer
listing with menuoid buffer selection.

If the very next character typed is a space then the buffer list
window disappears.  Otherwise, one may move around in the buffer list
window, marking buffers to be selected, saved or deleted.

To exit and select a new buffer, type a space when the cursor is on
the appropriate line of the buffer-list window.  Other commands are
much like those of `Buffer-menu-mode'.

Run hooks in `electric-buffer-menu-mode-hook' on entry.
"

*I like that typeoutoid and menuoid lingo. It doesn't sound like RMS's
style.

Then in ebuff-menu.el I noticed the the setq of truncate-lines which
seemed like a likely candidate for explaining the behavior you weren't
liking:
...
 (make-local-variable 'Helper-return-blurb)
  (setq Helper-return-blurb "return to buffer editing")
  (setq truncate-lines t)
  (setq buffer-read-only t)
  (setq major-mode 'Electric-buffer-menu-mode)
...

Btw, see earlier caveats about messing with .el files in emacs/lisp.
