[PATCH 2/2] emacs: tag-jump: make the same binding do the reverse tag change map

[Mark Walters]

Make the binding for going to the reverse tag change jump menu the
same as the binding to enter the tag-jump menu.

>From the way the tag-jump menu is setup it is relatively hard for the
user to configure this otherwise.
