[issue21193] pow(a, b, c) should not raise TypeError when b is negative and c is provided

[Josh Rosenberg]

Josh Rosenberg added the comment:

Here's the trivial patch for code and the associated unit test (we were actually testing that it raised TypeError specifically; it now raises ValueError, and the unit test expects ValueError).

unit tests passed aside from test_io, but I'm pretty sure that's unrelated; my Linux VM freezes up once in a while, which does nasty things to timing dependent I/O tests.
