[Python-Dev] Issue #16153: PyUnicode_FromFormatV() must fail if the format string is invalid

Hi,

Does anyone know if there is a good reason why PyUnicode_FromFormatV()
does not fail on invalid format string, but copies the format string
as-if into the result?

I would like to change this to raise a ValueError instead.
PyUnicode_FromFormatV() is used by PyErr_Format(), so PyErr_Format()
may now fail with a ValueError if the format string is invalid.

Victor
