When nodes are in different files, visiting all ancestor nodes means
visiting several files that is slow on slow machines/connections.
For instance, the first node in the file info/emacs-4 is:
File: emacs, Node: Fortran Indent, Next: Fortran Comments, Prev: Fortran
Motion, Up: Fortran
31.13.2 Fortran Indentation
So to display this node, it needs to open the file info/emacs-3 that
contains its parent node Fortran, and the top file info/emacs-1.

I see that with the shallow structure of Info manuals, most breadcrumbs
will just duplicate the Up: node reference in the header line.

Yes, I know. That's why I think "breadcrumbs" is an inappropriate name
for this feature. Unfortunately, it is already too widespread on the Web.
