This looks like a no-op hunk, unless format_paging_nav sub has other uses
of $has_more_pages variable.  But the copies of gitweb I have do not begin
with these lines, but they begin like this:

        sub format_paging_nav {
                my ($action, $hash, $head, $page, $nrevs) = @_;
                my $paging_nav;

On what version is your patch based on?  I checked warthog9's copy and
that also seems to be different.

I am not very good at counting, but the change looks no-op to me.  Either
the last index of the list variable is strictly larger than 99, or it is
100 or greater --- aren't they the same thing?

A bit confused I am...
