It's not a TDS-level issue.  We get an error message from the server,
which causes us not to set up results, hence no res_info.  

The message above is produced by tds_process_end():

        tdsdump_log(TDS_DBG_FUNC, "%L tds_process_end() more_results = %d,
was_cancelled = %d \n", more_results, was_cancelled);
        if (tds->res_info) {
                tds->res_info->more_results = more_results;
                if (tds->curr_resinfo == NULL)
                        tds->curr_resinfo = tds->res_info;

        }

meaning there isn't alwasy a res_info structure into which to save the
more_results status.  I made dbmorecmds follow suit, and now it doesn't
segfault.  

The bad news (for me) is that sp_help is obviously no help.  So the unit
test needs more work. :-(
