why is it that in scm_m_case (and some other macro transformers as well) a
scm_list_copy of the form is created and worked with?  scm_m_case does not
modify the form.  In scm_m_cond, however, the form is modified, but the
modification happens in a way that the list copying does not prevent the
original form from getting modified.

I suspect these copies are not necessary any more.
