6d65df1e8a Internal plumbing changes for float parsing:
- check for nans and infs within PyOS_ascii_strtod

ad476dab09 Issue #5816: Simplify code for parsing and printing of complex numbers.
nans and infs are no longer given special treatment; as a result,
repr(complex(z)) recovers z for any complex number z.

0923d1d8d7 The other half of Issue #1580: use short float repr where possible.
Addresses the float -> string conversion, using David Gay's code which
was added in Mark Dickinson's checkin r71663.

Also addresses these, which are intertwined with the short repr
changes:

- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'
- Issue #5515: 'n' formatting with commas no longer works poorly
    with leading zeros.
- PEP 378 Format Specifier for Thousands Separator: implemented
    for floats.

a3b1ac8dca Added ',' thousands grouping to int.__format__. See PEP 378.
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).

  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.
