[New-bugs-announce] [issue19984] Add new format of fix length string for PyErr_Format

[Vajrasky Kok]

New submission from Vajrasky Kok:

This ticket sprung from this discussion:
https://mail.python.org/pipermail/python-dev/2013-December/130756.html

Basically I am always confused when writing error message in C-API.

Is it:

PyErr_Format(PyExc_TypeError,"can't intern %.400s", s->ob_type->tp_name);

or

PyErr_Format(PyExc_TypeError,"can't intern %.80s", s->ob_type->tp_name);

or

PyErr_Format(PyExc_TypeError,"can't intern %s", s->ob_type->tp_name);

In conclusion, is it %s or %.80s or %.400s?

This patch will add one true way of writing fixed length string of the wrong type. This is just preliminary patch. I'll write the documentation later (and maybe test?).
