PyArg_ParseTuple raises inconsistent overflow error messages for small integer formats. For example:

>>> import _testcapi
>>> _testcapi.getargs_b(100)
100
>>> _testcapi.getargs_b(1000)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
OverflowError: unsigned byte integer is greater than maximum
>>> _testcapi.getargs_b(-1000)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
OverflowError: unsigned byte integer is less than minimum
>>> _testcapi.getargs_b(100000000000000000000)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
OverflowError: Python int too large to convert to C long
>>> _testcapi.getargs_b(-100000000000000000000)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
OverflowError: Python int too large to convert to C long

On platforms with 32-bit int and 64-bit long there will be more such cases.
