It seems the qmaster has some intelligent code and tries to optimize the job
structure for array tasks. This leads to other job ranges than used on the
commandline and can confuse customers.

Example:
qsub -t 1-100 $SGE_ROOT/examples/jobs/sleeper.sh
qalter -h 10 <jobid>
qalter -h 20-100 <jobid>
results in:
JB_ja_u_h_ids        (List)      = full {

   List: <task_id_range> * #Elements: 2
   -------------------------------
   RN_min               (Ulong)     = 10
   RN_max               (Ulong)     = 20
   RN_step              (Ulong)     = 10
   -------------------------------
   RN_min               (Ulong)     = 21
   RN_max               (Ulong)     = 100
   RN_step              (Ulong)     = 1
}

qstat outputs:
