This introduces a new bug: If empty_value is not None and the queryset is not a SearchQuerySet, no action will be taken at all.

Also, PEP 8:

> Long lines can be broken over multiple lines by wrapping expressions in parentheses. These should be used in preference to using a backslash for line continuation.
