[issue22597] printf-style formatting allows mixing keyed and keyless specifiers

[Jakub Wilk]

New submission from Jakub Wilk:

>>> '%(eggs)s %s' % {'eggs': 'ham'}
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: not enough arguments for format string

>>> '%s %(eggs)s' % {'eggs': 'ham'}
"{'eggs': 'ham'} ham"

I would expect a raised exception also in the latter case.
