[issue11587] METH_KEYWORDS alone gives "METH_OLDARGS is no longer supported!"

[Antti Haapala]

Antti Haapala added the comment:

This is *still* there in Hg tip: PyCFunction_Call in Objects/methodobject.c does not have a case for `METH_KEYWORDS` only at all.

The documentation for METH_KEYWORDS says that it is *typically* coupled with METH_VARARGS; however not having the case means that METH_KEYWORDS *cannot* be used without METH_VARARGS at all.

Furthermore, the default case should actually report the wrong flags value instead of calling it the "METH_OLDARGS", since it can be caused by any future combination, by setting it to zero, or undefined behaviour causing the flag to be overwritten.
