Cleanup Python-ast.c generation.

breaks the parser module, because it adds the if/else construct as well as
two new grammar rules for backward compatibility. If no one else fixes
parsermodule, I guess I'll go ahead and fix it later this week.

The TeX code was checked with texcheck.py, but not rendered. There is
actually a slight incompatibility:

>>> (x for x in lambda:0)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: iteration over non-sequence

changes into

>>> (x for x in lambda: 0)
  File "<stdin>", line 1
    (x for x in lambda: 0)
                     ^
SyntaxError: invalid syntax

Since there's no way the former version can be useful, it's probably a
bugfix ;)

Implement change suggested by Jiwon Seo on python-dev.
['(' gen_for ')'] is redundant with test, so remove it.

a tree of Python objects. Expose this through compile().

automatically removed.

Also annotate what each line is meant to test.

  - The copy module now "copies" function objects (as atomic objects).
  - dict.__getitem__ now looks for a __missing__ hook before raising
    KeyError.
  - Added a new type, defaultdict, to the collections module.
    This uses the new __missing__ hook behavior added to dict (see above).

Just symlink or copy python.vim to ~/.vim/syntax/ .  Also included is a sample
Python file with basic expressions to make sure they are highlighted.

Also add a Vim directory in Misc to hold all Vim configuration files.

build for the current CPU.

MacOSX 10.4 readline, and don't build the readline module in that case.
