Look at the uniquify- family of functions (especially the reverse
style), or Options >  use directory names in buffer names, or
buffers-menu-show-directories variable. If you really have buffer names
based on very long file names (part after last slash in fully qualified
path) then you might want to comment out the truncate-lines setq in
ebuff-menu.el I don't know if this is a good idea but Emacs is robust
enough that if that doesn't work, you could later set it back by using
touch -r on ebuff-menu.el to set its times back to something earlier
than ebuff-menu.elc
