Subject: Mark last BSS entry by #### instead of ====

Mark last BSS entry by #### instead of ====

This allows ctrl_iface users to iterate through the BSS entries by
fetching multiple BSS entries with "BSS RANGE=N-" without having to use
one extra round to get empty return value as the indication of the last
entry having been found.
