     We'd need to do so, and then restore it for CLEAR
     TRANSFORMATIONS.

Spss doesn't do this.  So neither should we (at least not by default).
     
     Second, some transformations are not exposed to the user and
     should not be cleared.  The specific one I have in mind is the
     DESCRIPTIVES transformation that produces Z scores.  As far as
     the user is concerned that transformation doesn't exist so it
     shouldn't be cleared.

Is this really an issue?  These transformations only come into
existance after the command has been called, and are destroyed before
it terminates, so there's no possibility that CLEAR TRANSFORMATIONS
can affect this.
