controls whether tests are included for objects with empty docstrings.
Defaults to True, to match the behavior of Python 2.3.

doctest always promised to stick "__test__" in the name.  That got
broken.  Now it's fixed again.

the "backward compatibility" here was a joke.

was passed.

The list resizing scheme only downsized when more than 16 elements were
removed in a single step:  del a[100:120].   As a result, the list would
never shrink when popping elements off one at a time.

This patch makes it shrink whenever more than half of the space is unused.

Also, at Tim's suggestion, renamed _new_size to new_allocated.  This makes
the code easier to understand.

- Dictionary keys are in arbitrary order, but not random (which implies, well,
  intentional randomness).
- Move a footnote closer to what it's talking about so that it doesn't look
  like we're saying that "0 == 0.0" can't be relied on.
- Minor language tweaks in the vicinity.

Thanks Dima Dorfman!

functions and methods now, including functions defined inside doctests
in test_doctest.py's recursive doctest'ing.

- accomodate -> accommodate
- occured -> occurred

Thanks George Yoshida!

(functions and methods have grown the __module__ attribute too). See bug #570300.

Template and unicode classes.

Add script dealing with REGISTRY.tcl installation

- Template no longer inherits from unicode.

- SafeTemplate is removed.  Now Templates have both a substitute() and a
  safe_substitute() method, so we don't need separate classes.  No more
  __mod__() operator.

- Adopt Tim Peter's idea for giving Template a metaclass, which makes the
  delimiter, the identifier pattern, or the entire pattern easy to override
  and document, while retaining efficiency of class-time compilation of the
  regexp.

- More informative ValueError messages which will help a user narrow down the
  bogus delimiter to the line and column in the original string (helpful for
  long triple quoted strings).

this caused duplicate attributes for the bottom navigation panel.

Install python[w].exe on demand also as extpy[w].exe

Also added a comment about why the code is bother to see what setlocale thinks
the set locale is.

Closes bug #1023798.

decoding incomplete input (when the input stream is temporarily exhausted).
codecs.StreamReader now implements buffering, which enables proper
readline support for the UTF-16 decoders. codecs.StreamReader.read()
has a new argument chars which specifies the number of characters to
return. codecs.StreamReader.readline() and codecs.StreamReader.readlines()
have a new argument keepends. Trailing "\n"s will be stripped from the lines
if keepends is false. Added C APIs PyUnicode_DecodeUTF8Stateful and
PyUnicode_DecodeUTF16Stateful.
