Issue #5793: rationalize isdigit / isalpha / tolower, etc. Will port to py3k. Should fix Windows buildbot errors.
........
problems for binary distributions of Python in situations
where the build machine has SSE2 but the target machine
does not.
Therefore, don't enable SSE2 instructions automatically on x86.
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.
- incorporate and adapt David Gay's dtoa and strtod
into the Python core
- on platforms where we can use Gay's code (almost
all!), repr(float) is based on the shortest
sequence of decimal digits that rounds correctly.
- add sys.float_repr_style attribute to indicate
whether we're using Gay's code or not
- add autoconf magic to detect and enable SSE2
instructions on x86/gcc
- slight change to repr and str: repr switches
to exponential notation at 1e16 instead of
1e17, str switches at 1e11 instead of 1e12

In PyErr_GivenExceptionMatches, temporarily bump the recursion
limit, so that in the most common case PyObject_IsSubclass will
not raise a recursion error we have to ignore anyway.

PyErr_NormalizeException may not set an error, so convert the PyErr_SetObject
call on hitting the recursion limit into just assigning it to the arguments provided.
........
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).
