----------------
Can you clarify why this is changing in this patch? It’s not obvious to me why 
this would start optimizing internal whitespace of macros. 

(I also can’t remember if it’s safe/correct. Is there a way to stringify the 
contents of a macro? If so, this would change the result… if not, then this 
seems like an improvement, but maybe better for a separate patch?)

(If there’s a good reason to change it here, don’t want to hold it up, but it’s 
not explained in the commit message so it’s not obvious to me.)
