Use METH_NOARGS instead of METH_VARARGS; as written, this code will accept
any number of arguments to the Python use_default_colors() method and not
raise any error.  An alternative would be to leave METH_VARARGS and put "if
(!PyArg_NoArgs(args)) return NULL;" in pyuse_default_colors(); this would
work with older versions of Python at the cost of being slightly slower.

I'll add this function to the curses module, so at least it'll be in 2.4;
thanks for writing it. Anyone know if it's possible to test it on MacOS X?
Does the Terminal support transparency?
