改进版，判断行尾字符决定是 insert 还是 remove，支持多行：

(defun insert-or-remove-trailing-char (&optional ch)
  (interactive)
  (let ((ch (or ch (read-char "Input char: ")))
        (fn (lambda (ch)
              (end-of-line)
              (if (eq (char-before) ch)
                  (delete-backward-char 1)
                (insert-char ch)))))
    (save-excursion
      (if (region-active-p)
          (save-restriction
            (narrow-to-region (region-beginning) (region-end))
            (deactivate-mark)
            (goto-char (point-min))
            (funcall fn ch)
            (while (< (point) (- (point-max) 1))
              (next-line)
              (funcall fn ch)))
        (funcall fn ch)))))

(defun insert-or-remove-trailing-semi ()
  (interactive)
  (insert-or-remove-trailing-char ?\;))

(defun insert-or-remove-trailing-comma ()
  (interactive)
  (insert-or-remove-trailing-char ?,))
