+ line number information associated with the lines within
+ the macro definition, but we would need more infrastructure
+ to make that happen correctly (e.g. resetting the line
+ number when expanding the macro), and since for short
+ macros we clearly prefer reporting the point of expansion
+ anyway, there's not an obviously better fix here. */
