I've just noticed this here, and now I'm starting to wonder:
is there something strange in the software I have here now,
that I didn't notice this before?  I could have sworn that this
worked before.  Perhaps a bug with my su alias (sets different history
file?)  Perhaps a mis-directed binary patch?
