[issue13454] crash when deleting one pair from tee()

[Georg Brandl]

Georg Brandl added the comment:

The patch replaces a

 Py_CLEAR(tdo->nextlink)

with a construct that does, basically, something like this several times:

 Py_DECREF(tdo->nextlink)
 tdo->nextlink

which is what leads to the issues that Py_CLEAR is supposed to prevent.  Therefore I think this patch is not correct.
