Summary: getnext and header_simple_table()

Initial Comment:
In agent/mibgroup/util_func.c header_simple_table() appears to have a problem with getnext for 
oid with a longer length than expected. 

For example: the following command returns the following:
snmpgetnext -p 175 10.0.0.42 public system.sysORTable.sysOREntry.sysORUpTime.1.1

interfaces.ifNumber.0 = 31

It should return the value for sysOrUpTime.2.

This is utilizing UCD SNMP 4.2 on a Linux PPC system.
