Subject: bug#5998: 23.1.96; Breadcrumbs defeat C-u 1 C-v in Info
Date: Wed, 21 Apr 2010 20:18:34 +0300

 emacs -Q

 C-u 1 C-v

Note that the display does not scroll by one line.  "C-u 2 C-v" does
scroll by 2 lines, as well as "C-u 1 C-v" if the breadcrumbs are not
visible.

You can see this in any node, not just in Narrowing, of course.
