Was the 'sniff' word-concept a Bruce invention ?

Because, if so, its such a neat idea, that we owe him at least some wine
in paris for inventing it.

Incedentally, this idea of sniffing, I understand it because I see it,
but I wonder if it isn't more of a fast-eval-searcher concept. liek my
program tends not to sniff things, but to either find them of not. I
guess that since fast evals are getting many of their positional
concepts from the search, you'ld expect to see a gradual 'sniffing' as
the plies deepen; while a knowledge prg would just tend to grab it on
finding it .... ?
