Comment(by slabbe):
So, now, I can say that I give a positive review to this ticket if the
following 5 lines of `E1Star.__init__` are removed.
{{{
# changing the alphabet of sigma to [1, ..., d]
A = sigma.domain().alphabet()
change_alphabet = WordMorphism(dict([(A[i], [Integer(i+1)]) for i
in range(len(A))]))
D = dict([(change_alphabet(a)[0], list(change_alphabet(sigma(a))))
for a in A])
sigma = WordMorphism(D)
}}}
Of course, my two patches also have to get a positive review by Timo or
Alexandre (preferably both) before the ticket be ready to be merged into
Sage.
