Handle references to line data in _patiencediff_c.c properly
This code is called in bzrlib only with lists or tuples of strings, which works fine, because PySequence_Fast always returns the same object and so the items from PySequence_Fast_GET_ITEM will not be deleted until the original sequence is deleted. But if it's called with a sequence than needs to be converted to list (e.g. PyUnicode), the items will be garbage collected in the contructor and still used later in code (which leads to segfaults).
