This history ring grows from 0..$history, with last marking the where new entries go:
Once the array fills up, it is used as a ring. last points where a new entry will go. Older entries are "up", and wrap around:
When $history_remove_dups is set, duplicate entries are scanned and removed each time a new entry is added. In order to preserve the history ring size, entries 0..last are compacted up. Entries last+1..$history are compacted down:
