You are aware that you are in agreement with me?  The increased memory
usage is _exactly_ why one would have to limit the history depth "to
something reasonable".

I see no actual point moving the history into strings from buffers and
back again: easier to just keep the buffers.  Also much more transparent
to reclaim memory if you run out of it: you can find and delete large
buffers, but you won't easily figure out that some history string is
eating all your memory.
