commit 13762d24b88a370f349d308c48b28b94bcbbad18
Author: Po Lu <luangruo@yahoo.com>
Commit: Po Lu <luangruo@yahoo.com>
Display drag-and-drop messages in echo area on non-graphics displays
* lisp/mouse.el (mouse-drag-and-drop-region-display-tooltip)
(mouse-drag-and-drop-region-hide-tooltip): New functions.
(mouse-drag-and-drop-region): Use them instead of calling
`x-hide-tip' and `x-show-tip' directly.
