Re: [PATCH 2/3] format_config: simplify buffer handling

I wonder if we can do this instead

	if (!omit_values) {
-		if (show_keys)
+		if (show_keys && value_)
			strbuf_addch(buf, key_delim);

though.  That would eliminate the need for rolling back.

No we cannot.  "config --bool --get-regexp" could get a NULL value_
and has to turn it to " true".

Sorry for the noise.
