Am I correct in guessing that the arguments to - in the Lisp-code definition
of short-float-negative-epsilon in the Laser edition are backwards?  The
code as it stands is clearly bogus.  If the arguments to - are backwards,
then negative-epsilon would be the smallest positive number that you
can subtract from 1.0 and get a different answer than 1.0.

This hasn't been fixed in the latest version of the manual we have.
