Subject: [PATCH 8] gitweb: Add git_page_nav for later use
Message-ID: <200607301459.58032.jnareb@gmail.com>
In-Reply-To: <200607292239.11034.jnareb@gmail.com>

Adds git_page_nav subroutine to factors out the generation of the
navigation bar.  Based on Sven Verdoolaege code
  Message-Id: <20050618113121.GA13122@pc117b.liacs.nl>
  http://marc.theaimsgroup.com/?l=git&m=111909432415478&w=2

I tried for the refactored navbar generate the same result.
