} By "done internally," you mean to have makehistory always have the -u

} mean something else?

Ouch, I should have looked into the code more carefully.  
That was my over thought.  Sorry for confusing.  But I'd
say -u should not be used for buffindexed, since it just
appends index/data and this means occupied buffer will
grow to over double size until next expireover.  As to
tradindexed, data (not index) is also appended and the
same problem occurs.
