squarefree part.
Okay, assuming I read the definition correctly, the two versions should
now agree. Unfortunately, I don't know how to test if that's the case,
since integers don't implement `squarefree_decomposition()`.

I found no mention of `elementary_divisor()` anywhere in the sage source
code, so I guess there won't be the same problem. Off course, there could
always be another inconsistency regarding who knows what convention or
definitions, like there are so many in sage!
