> WordDelimiterFilter and WordDelimiterGraphFilter behave almost identically outside setting position length; the only difference being that WDGF can sometimes emit its original token as the second output token rather than the first. We should change this to conform to the behaviour of the older filter - this will make it much easier to remove WDF entirely and cut over tests that use it incidentally.
