No, there is no standard configuration that does this.  I offered it to Emacs
Dev several times starting a long time ago (and it is still offered), but there
has never been insufficient interest.

But you can get it here - just load library `info+.el'.  It should work with GNU
Emacs versions 20 through 24.  A few of the features, such as breadcrumbs, have
been added to Emacs, but not the highlighting.
