Log Message:
Bugfix for strict datatypes in the (old) tracing transformation.
Previously, a type like
    data AB a = C !a !a
was transformed to
    data AB a = C (R !a) (R !a)
This type is incorrect, but appeared in interface files nevertheless,
whence it could not be parsed back in.  This fix makes the
transformation produce the type
    data AB a = C !(R a) !(R a)
which is also somewhat incorrect (or misleading) but is actually parsable.
