+**  SM_STRINGF_X -- printf() to dynamically allocated string.

+**	It raises an exception on error.
+**	The name comes from a PWB Unix function called stringf.
+**
+**	Parameters:
+**		fmt -- format string.
+**		... -- arguments for format.
+**
+**	Returns:
+**		Pointer to a dynamically allocated string.
+**
+**	Exceptions:
+**		F:sm_heap -- out of memory (via sm_vstringf_x()).
