From 35d2d241554de1928235edabc848419cc088e02c Mon Sep 17 00:00:00 2001

Subject: [PATCH] (Info-fontify-node): For menu items, use info-xref font. Use
 info-node font for the node's own name, and do not make it mouse-sensitive.

(Info-find-node): Update Info-history after switching buffer.
(info): If no arg, and *info* buffer exists, just go to it and don't alter it.
