[Python-ideas] Fix some special cases in Fractions?

[Jonathan Fine]

Hi Neil

When I wrote my previous message, I didn't know who you were, or your
previous contributions. Perhaps I should have. But I didn't.

If I had known, my remarks would have been different. In particular, I
would have acknowledged your previous contributions. I apologise for
any offence I may have caused you.

Better late than never. Thank you for your contributions to
implementing PEP 448.

with best regards

Jonathan
