'<' currently only applies to niced processes.  I think there should
be different indicators for realtime and idle priority and other
scheduling classes.

In top(1), scheduling classes are supposed to be encoded as fake
nice values and a single indicator almost works since the indicator is
numeric so it can indicate the scheduling class; however, the encoding
is limited and broken; a non-numeric indicator of the class combined
with a shorter numeric indicator of the the priority within the class
might be better.
