PyErr_Format() these new C API methods can be used instead of
sprintf()'s into hardcoded char* buffers. This allows us to fix
many situation where long package, module, or class names get
truncated in reprs.
PyString_FromFormat() is the varargs variety.
PyString_FromFormatV() is the va_list variety
Original PyErr_Format() code was modified to allow %p and %ld
expansions.
Many reprs were converted to this, checkins coming soo. Not
changed: complex_repr(), float_repr(), float_print(), float_str(),
int_repr(). There may be other candidates not yet converted.
Closes patch #454743.
super(type) -> unbound super object
super(type, obj) -> bound super object; requires isinstance(obj, type)
Typical use to call a cooperative superclass method:
class C(B):
def meth(self, arg):
super(C, self).meth(arg);
the delete function. (Question: should the attribute name also be
recorded in the getset object? That makes the protocol more work, but
may give us better error messages.)

powu: Deleted.
This started with a nonsensical error msg:
>>> x = -1.
>>> import sys
>>> x**(-sys.maxint-1L)
Traceback (most recent call last):
File "<stdin>", line 1, in ?
ValueError: negative number cannot be raised to a fractional power

The special-casing in float_pow was simply wrong in this case (there's
not even anything peculiar about these inputs), and I don't see any point
to it in *any* case: a decent libm pow should have worst-case error under
1 ULP, so in particular should deliver the exact result whenever the exact
result is representable (else its error is at least 1 ULP). Thus our
special fiddling for integral values "shouldn't" buy anything in accuracy,
and, to the contrary, repeated multiplication is less accurate than a
decent pow when the true result isn't exactly representable. So just
letting pow() do its job here (we may not be able to trust libm x-platform
in exceptional cases, but these are normal cases).

ChipWidget.__init__(): Added a message area just below the color
name. Both the message and name widgets are now FLAT, DISABLED
Entry widgets instead of Labels. This allows users to
copy-n-paste the color names or color specs. Also, the contents
of both widgets are now driven by StringVars.
set_color(): This only sets the chip color; it does not set the name
widgets.
set_name(): New method which only sets the name widget contents.
set_message(): New method which only sets the message widget contents.
ChipViewer.update_yourself(): Set the color, name, and message for
each chip as follows: the first line always contains the color
spec in #rrggbb format. The second line will contain the color
name, but slightly differently for each widget. For the Selected
widget, if the color exactly matches the Nearest color, the name
is shown, otherwise the message field will be empty. The name
field of the Nearest widget will always contain the color name.
