[docs] [issue12842] Docs: first parameter of tp_richcompare() always has the correct type

[Stefan Krah]

New submission from Stefan Krah <stefan-usenet at bytereef.org>:

I've noticed that assumptions about the operand types in tp_richcompare()
are not always consistent. As far as I can see, the first parameter
in tp_richcompare() is guaranteed to be of the correct type.

But in some places the first parameter's type is still checked:

Objects/cellobject.c:

    if (!PyCell_Check(a) || !PyCell_Check(b)) {


The attached patch makes it clear that the first parameter has
the correct type.
