CustomRequestLog %q inconsistency with a doc

Description
Javadoc says:

%q The query string, prepended with a ? if a query string exists, otherwise an empty string.

Meanwhile the code is:

    private static void logQueryString(StringBuilder b, Request request, Response response)
    {
        append(b, "?" + request.getHttpURI().getQuery());
    }

Append is unconditional which renders empty query string as ?null

How to reproduce?

I wonder if this should produce just a - if there is no query string?
