[PATCH 19/21] userformat_want_item(): mark unused parameter

This function is used as a callback to strbuf_expand(), so it must conform to the correct interface. But naturally it doesn't need to touch its "sb" parameter, since it is only examining the placeholder string, and not actually writing any output. So mark the unused parameter to silence -Wunused-parameter.
