[PATCH] gitweb: only display "next" links in logs if there is a next page

[Lea Wiemann <lewiemann@gmail.com>]

There was a bug in the implementation of the "next" links in
format_paging_nav (for log and shortlog), which caused the next links
to always be displayed, even if there is no next page.  This fixes it.
