       form: a `formula' object.

        sep: an optional character string specifying the sepa-
             rator to be used for splitting the formula.
             Defaults to `"/"'.

        Splits the right hand side of `form' into a list of
        subformulas according to the presence of `sep'. The
        left hand side of `form', if present, will be ignored.
        The length of the returned list will be equal to the
        number of occurrences of `sep' in `form' plus one.
