After updating my patch, I've decided that %s works better. My
patch implements PEP 461 as proposed with the following additional
- add %a format code, calls PyObject_ASCII on the argument. I
see no reason not too add it as a useful debugging feature.
- add -2 command-line option. When enabled: %s will fallback
to calling PyObject_Str() after first trying the buffer API
and __bytes__. The value will be encoded using strict ASCII
encoding. Also, %r is enabled as an alias for %a.
The patch is v4, bugs.python.org/issue20284, still needs more review
