Question marks at the end swallowed

Looks like the example with just question marks is good now:

>>> segmenter.segment("??") ['??']

but the example with double question marks as a token at the end of a sentence still loses the question marks:

>>> segmenter.segment("T stands for the vector transposition. As shown in Fig. ??") ['T stands for the vector transposition.', 'As shown in Fig.']

looks like this is the minimal repro:

>>> segmenter.segment("Fig. ??") ['Fig.']
