Comment (by darij):
Thanks for fixing these!
What about this, do we consider it a bug?
{{{
sage: sage: P1 = DiGraph({1:{2:['a']}}).path_semigroup()
sage: sage: P2 = DiGraph({1:{2:['a','b']}}).path_semigroup()
sage: sage: A1 = P1.algebra(GF(3))
sage: sage: A2 = P2.algebra(GF(3))
sage: e1, e2, a, b = A2.gens()
sage: A1(b)
b
sage: list(A1.basis())
[e_1, e_2, a]
}}}
(This is a conversion, not a coercion, map, at least.)
