Ding dong!

;;;;;;;;;; test.el ;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
(require 'bs)
(add-hook 'bs-mode-hook (lambda () (set-window-fringes nil 0 0)))
(setq bs-attributes-list '(("Buffer" compute-buffer-width  nil left
bs--get-name)))
(defun compute-buffer-width ()
  (- (window-width)
     1))  ; one empty column at the end
;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;,,,,,,,,

emacs -Q -l test.el -f bs-show

Result: there's a spurious blank line at the end which wasn't there in
24.1, nor the trunk of few days ago.
