Patch #25: Skip sprio display of jobs whose priority has been

            set directly (since the priority factor fields are 0).

rity/multifactor: skip jobs whose priority has been set directly

This avoids displaying "house numbers" in sprio if the priority has been
set directly, as in the following example for aghasemi (whose group is a
"bottom-feeder" with a fixed priority of 10):
