* Fix failure of _Py_dg_dtoa to remove trailing zeros
* Add regression test and news entry
* Add explanation about why it's safe to strip trailing zeros
* Make code safer, clean up comments, add change note at top of file
* Nitpick: avoid implicit int-to-float conversion in tests
Write a function to enable more optimizations:
* If the substring is the whole string and overallocation is disabled, just
keep a reference to the string, don't copy characters
* Avoid a call to the expensive _PyUnicode_FindMaxChar() function when
possible
- Use _PyLong_FormatWriter() instead of formatlong() when possible, to avoid
a temporary buffer
- Enable the fast path when width is smaller or equals to the length,
and when the precision is bigger or equals to the length
- Add unit tests!
- formatlong() uses PyUnicode_Resize() instead of _PyUnicode_FromASCII()
to resize the output string
* Decode thousands separator and decimal point using PyUnicode_DecodeLocale()
(from the locale encoding), instead of decoding them implicitly from latin1
* Remove _PyUnicode_InsertThousandsGroupingLocale(), it was not used
* Change _PyUnicode_InsertThousandsGrouping() API to return the maximum
character if unicode is NULL
* Replace MIN/MAX macros by Py_MIN/Py_MAX
* stringlib/undef.h undefines STRINGLIB_IS_UNICODE
* stringlib/localeutil.h only supports Unicode

Make global variable overflowok into a keyword argument; this fixes a failure when running ./python -m test.regrtest -R 3:2: test_format

Fix spacing nit. Thanks Eric Smith for the public humiliation.

Add missing global declarations for 'overflowok'; remove 'overflowrequired', which is no longer needed.

Actually raise on failure, instead of doing nothing.

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.
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.
