> Ideally, the first token of WDGF is the preserveOriginal (if configured to emit), and the second should be the catenateAll (if configured to emit).  The deprecated WDF does this but WDGF can sometimes put the first other token earlier when there is a non-emitted candidate sub-token.
> Example input "8-other" when only generateWordParts and catenateAll -- *not* generateNumberParts.  WDGF internally sees the '8' but moves on.  Ultimately, the "other" token and the catenated "8other" will appear at the same internal position, which by luck fools the sorter to emit "other" first.
