+ * string.
+ *
+ * @fixme There is a small leak here in that sometimes the existing
+ * value will be dynamically allocated, and the old copy is lost.
+ * However, we can't always deallocate the old value, because in the
+ * case of sDefault, it points to a static string. It would be nice
+ * to have either all-strdup'd values, or to never need to free
+ * memory.
