Allow LISTDEF to be used by REPAIR where appropriate at partition level that includes a range (1:50)

Allow LISTDEF with REPAIR, such as turning off AREO* (NOAREORPENDSTAR) at partition level. This would include a from partlevel to to partlevel. This would reduce the number of REPAIRs that need to be generated.
