commit 6b3f2dee7a3454193914bf80e3c7a102d68b15e5
Author: Bill Erickson <berick at esilibrary.com>
Date:   Wed Oct 5 09:39:47 2011 -0400

    Z39.50 local catalog fetch-more repairs
    
    Fixes the following problem:
    
    When paging through local catalog results in the Z39.50 interface,
    paging off then end of the local results would result in an unknown
    server error caused by trying to retrieve an empty list of records.
    
    $list->{count} in this context is the overall hit count, not the counts
    in the current page of results.  Note also if {count} is zero, the list
    of IDs will be undef, so we use both.
