OK, as the structure looks like

	struct output_state {
		char buffer[8193];
		int used;
		...

we obviously cannot initialize buffer[] with a single integer 0 ;-)
Between "" and "\0" you wondered elsewhere, I have no strong
preference, but if I were fixing it, I would probably write it as

	struct output_state output_state = { { 0 } };

so that readers do not even have to waste time to wonder between the
two.

Thanks.
