+       Make casewriters keep track of the number of `union value's in
+       each case.  This is useful for two reasons: casewriter_write can
+       then check that the case being written is large enough, and later
+       recipients of the casewriter can determine the size of the case.
+       
+       * casewriter-translator.c (casewriter_create_translator): Add
+       value_cnt parameter.
+       
+       * casewriter.c (struct casewriter): Add value_cnt member.
+       (casewriter_write): Check that the case passed in is big enough.
+       (casewriter_get_value_cnt): New function.
+       (casewriter_create): Add value_cnt parameter.
+
