I see my error now. I'm sorry for my ignorance. I will google how to delete the 
bugs item, but I guess is permanent, se la vie.
Thank you.

 New submission from Tim Peters:

 They already are.

 >>> (-2)**0
 1

 You're probably doing this instead:

 >>> -2**0
 -1

 Exponentiation has higher precedence than unary minus, so
 that last example groups as -(2**0), and -1 is correct.
