Another way might be to save the (just reloaded) recall buffer as a
separate file on entry to a session, then you just have to compare
that at any time later with the current recall buffer to know what's
been added or changed. Something like this must have been done years
ago though. Perhaps something on old decus tapes ?.

Usually have 2 or 3 terminal sessions running bash here, and they all have
unique history files. Not sure how that works though...
