#9588: Extend is_prime_power to negative exponents
--------------------------------+-------------------------------------------

--------------------------------+-------------------------------------------
Currently, is_prime_power only works on integers. The attached simple
patch will allow rational numbers as input as illustrated below.
{{{
sage: is_prime_power(1/2197)
True
sage: is_prime_power(1/100)
False
sage: is_prime_power(2/5)
False
}}}
This is also the behavior of Mathematica's PrimePowerQ function.
