This is incomplete, but I want to get some version into the next alpha. I am still working on:
Documentation.
More tests.
Implement for floats.
In addition, there's an existing bug with 'n' formatting that carries forward to thousands grouping (issue 5515).
The repr() of a string now contains printable Unicode characters unescaped.
The new ascii() builtin can be used to get a repr() with only ASCII characters in it.
PEP and patch were written by Atsuo Ishimoto.
svn+ssh://pythondev@svn.python.org/python/trunk
When forward porting this, I added _PyUnicode_InsertThousandsGrouping.

Addresses issue 2802: 'n' formatting for integers.
Adds 'n' as a format specifier for integers, to mirror the same
specifier which is already available for floats. 'n' is the same as
'd', but inserts the current locale-specific thousands grouping.
I added this as a stringlib function, but it's only used by str type,
not unicode. This is because of an implementation detail in
unicode.format(), which does its own str->unicode conversion. But the
unicode version will be needed in 3.0, and it may be needed by other
code eventually in 2.6 (maybe decimal?), so I left it as a stringlib
implementation. As long as the unicode version isn't instantiated,
there's no overhead for this.

formatting.
Includes:
- Modifying tests for basic types to use __format__ methods, instead
of builtin "format".
- Adding PyObject_Format.
- General str/unicode cleanup discovered when backporting to 2.6.
- Removing datetimemodule.c's time_format, since it was identical
to date_format.
The files in Objects/stringlib that implement PEP 3101 (stringdefs.h,
unicodedefs.h, formatter.h, string_format.h) are identical in trunk
and py3k. Any changes from here on should be made to trunk, and
changes will propogate to py3k).
to be called a buffer). Shares code with stringobject when possible.
Adds unit tests with common code that should be usable to test the PEPs
mutable buffer() and immutable bytes() types.

Known issues:
The string.Formatter class, as discussed in the PEP, is incomplete.
Error handling needs to conform to the PEP.
Need to fix this warning that I introduced in Python/formatter_unicode.c:
Objects/stringlib/unicodedefs.h:26: warning: `STRINGLIB_CMP' defined but not used
Need to make sure sign formatting is correct, more tests needed.
Need to remove '()' sign formatting, left over from an earlier version of the PEP.
