Info navigation is broken

[David Ponce]

Hello,

Info navigation using [u]p, [n]ext, [p]rev commands is broken in
CVS version of Emacs 21.  Here is a backtrace:

Debugger entered--Lisp error: (error "Node has no Up")
 signal(error ("Node has no Up"))
 error("Node has no %s" "Up")
 Info-extract-pointer("up")
 Info-up()
* call-interactively(Info-up)

Also it seems that there are two header lines in the Info buffer, like
this:

File: dir, Node: Top This is the top of the INFO tree <== header line
File: dir, Node: Top This is the top of the INFO tree <== buffer

After commenting out the following line in `Info-setup-header-line'
Info navigation worked fine again.

;;; It is useful to be able to copy the links line out of the buffer
;;; with M-w.
;;;    (narrow-to-region (1+ header-end) (point-max))

Sincerely,
David
