If the user asks for --format=%G with nothing else, we correctly realize that "%G" is not a valid placeholder (it should be "%G?", "%GK", etc). But we still tell the strbuf_expand code that we consumed 2 characters, causing it to jump over the trailing NUL and output garbage. This also fixes the case where "%GX" would be consumed (and produce no output). In other cases, we pass unrecognized placeholders through to the final string.
