I nailed it down to this code

#!python

def merge_url_qs(url, **kw):
    """ Merge the query string elements of a URL with the ones in ``kw``.
    If any query string element exists in ``url`` that also exists in
    ``kw``, replace it."""
    segments = urlparse.urlsplit(url)
    extra_qs = ['%s=%s' % (k, v) for (k, v) in
                urlparse.parse_qsl(segments.query, keep_blank_values=1)
                if k not in kw]
    qs = ''
    for k, v in sorted(kw.items()):
        qs += '%s=%s&' % (k, v)
    if extra_qs:
        qs += '&'.join(extra_qs)
    else:
        qs = qs[:-1]
    return urlparse.urlunsplit(
        (segments.scheme, segments.netloc, segments.path, qs, segments.fragment)
    )
