+ * Example:
+ *     // Print arguments as a JSON array.
+ *     #include <ccan/json_escape/json_escape.h>
+ *
+ *     int main(int argc, char *argv[])
+ *     {
+ *             printf("[");
+ *             for (int i = 1; i < argc; i++) {
+ *                     struct json_escape *e = json_escape(NULL, argv[i]);
+ *                     printf("%s\"%s\"", i == 1 ? "" : ",", e->s);
+ *             }
+ *             printf("]\n");
+ *             return 0;
