bug#23749: 24.3.50; can't make the cursor to the end of a buffer when that buffer is visible

[Noam Postavsky]

Cool, could be compacted a little:

(defun insert-into-buffer (buffer text)
  (with-current-buffer buffer
    (beginning-of-line)
    (insert text)
    (let ((buffer-window (get-buffer-window)))
      (if buffer-window
          (set-window-point buffer-window (point-max))
        (goto-char (point-max))))))
