Comment:
The new patch applies fine to 4.3.1, and *almost* all tests pass. (I
tested the whole Sage library):

file format since FiniteWord_over_OrderedAlphabet is deprecated and will
be deleted in a future version of Sage (you can use FiniteWord_list
instead). You can re-save your word by typing "word.save(filename)" to
ensure that it will load in future versions of Sage.
