I cannot tell if this part is tongue-in-cheek (especially the "++"),
so I will ignore it to avoid wasting time.

I am not sure what negative impact you think the macro-ness would
have to the validity of the result from this test balloon.  An old
compiler that does not understand designated initializer syntax
would fail to compile both the same way, no?

	struct strbuf buf0 = STRBUF_INIT;
	struct strbuf buf1 = { .alloc = 0, .len = 0, .buf = strbuf_slopbuf };
